Logic of Statistical Significance - Essay Example Taking a sample of 1000 people, the nominal survey data collected is as shown: Suppose the null hypothesis is gender and preferences are independent. Then on evaluating the test statistics, getting a value of 16.2 using the degree of freedom of 2. Comparing this t-statistic with the critical value obtained from the chi- distribution table, suppose the significance level of 0.05 is chosen. Then it can be ascertained that the finding is significant as the t-statistic is higher than the critical value. This leads to the rejection of the null hypothesis and also the arrival of a conclusion that there exists a relationship between preferences and gender for that product. For the case of ordinal data survey, as in the example of a survey comparing the mean weights of male and female students. A statistical hypothesis test is used for making decisions on the data. The test result is calculated from the null hypothesis. The test sample is said to be statistically significant if its occurrence is unlikely to have been by chance alone. The statistically significant result that is given by probability p-value is less than the threshold of a significant level then it justifies the rejection of the null hypothesis. Once the variations have been attained, the Fischer value is calculated and is compared to the f critical value from the table at a given degree of confidence (Carlson, 1976). Another important concept to consideration is the use of one-tailed or two-tailed significance tests. (StatPac Inc, 2012) The hypothesis determines the selection of each. If the hypothesis gives directions, for example, men generally weigh more than women then the one-tailed significance test is employed. However, if the hypothesis gives no directions as in the example, there is no significant difference in performances between boys and girls, and then the two-tailed significance test is used. The two-test probability is exactly twice the one-test probability

Tom’s closing speech in The Glass Menagerie -- English Literature Tenn

Tom’s closing speech in The Glass Menagerie Tom’s closing speech in The Glass Menagerie is very emotional and ironic. However, this monologue is somewhat ambiguous and doesn’t implicitly state whether Tom found the adventure he sought. It seems as though he never returned to St. Louis, and spent the remainder of his life wandering from place to place. This is inferred when he says,† I didn’t go to the moon, I went much further-for time is the longest distance between two places†¦Ã¢â‚¬  Throughout the play, the fire escape has been a symbol of Tom’s entrance and exit into both his reality and his dream world. He tells us that his departure marked the last time he â€Å"descended the steps of this fire-escape†, thus permanently embarking on his journey of solitude into what was once only a part of his dream world. From the statement, â€Å"(I) followed, from then on, in my father’s footsteps..† the reader can see that Tom acknowledges that he has chosen a path which is very similar to that of his father’s. In recognising this fact, Tom also admits that he abandoned his family just like Mr. Wingfield did. Tom’s journey does not seem to bring the escape and excitement that he had always longed for. He says, â€Å"The cities swept about me like dead leaves..† This description does not sound as though it comes from a traveller who is ecstatic about visiting different parts of the world. Cities are anything but dead; on the contrary, they are vibrant and full of life, and persons who are artistically inclined tend to be attracted to bustling cities. By categorising all the cities as dead leaves, Tom classifies them as similar entities in which he notices no individuality, uniqueness or excitement. He cannot relish in the beau... ...scape, and she will most likely carry this pain for the rest of her life. It also symbolises Tom’s final farewell to her. Essentially, this monologue reveals that Tom’s escape has not been as complete or as perfect as he had hoped. While he has escaped the physical limitations of the Wingfield apartment and the restrictions of his job at the warehouse, memories from his past and feelings of regret seem to create an intangible prison for Tom. He has been unable to remove himself from the coffin and leave all the nails untouched, as was his former desire. His statement of â€Å"I am more faithful than I intended to be!† alludes to the fact that he is fully cognisant that he has left his family to struggle with the consequences of his departure. The Glass Menagerie ends with Tom’s life being exactly opposite to the one he had foreseen when he planned his escape.

Legends Of Seismology :: essays research papers

Legends in Our Time Seismologists†¦ Scientists and Mathematicians Beno Gutenberg was the foremost observational seismologist of the twentieth century. He combined exquisite analysis of seismic records with powerful analytical, interpretive, and modeling skills to contribute many important discoveries of the structure of the solid Earth and its atmosphere. Perhaps his best known contribution was the precise location of the core of the Earth and the identification of its elastic properties. Other major contributions include the travel-time curves; the discovery of very long-period seismic waves with large amplitudes that circle the Earth; the identification of differences in crustal structure between continents and oceans, including the discovery of a significantly thin crust in the Pacific; the discovery of a low-velocity layer in the mantle (which he interpreted as the zone of decoupling of horizontal motions of the surficial parts from the deeper parts of the Earth); the creation of the magnitude scale for earthquakes; the relation between magnitu des and energies for earthquakes; the famous universal magnitude-frequency relation for earthquake distributions; the first density distribution for the mantle; the study of the temperature distribution in the Earth; the understanding of microseisms; and the structure of the atmosphere. Source: http://www.nap.edu/readingroom/books/biomems/bgutenberg.html Inge Lemann's primary accomplishments dealt with discoveries about the Earth's core. In 1936, she discovered that the Earth has a small inner core. Then she "saw" the area where earthquake waves did not pass through and reasoned that there must be an outer liquid core and an inner solid core. She was the first president of the European Seismological Commission. Lehmann was Denmark's only seismologist for two decades. And, in 1977, she became the first woman to be awarded the Medal of the Seismological Society of America. Source: http://www.physics.purdue.edu/wip/herstory/lehmann.html Charles Francis Richter started working at the Seismological Laboratory of the Carnegie Institution of Washington, based at Pasadena, California, in 1927. The following year, he was awarded a doctorate in theoretical physics by the Californian Institute of Technology (Caltech). During the 1930s, Richter was tabulating over 200 earthquakes a year in southern California at Caltech's Seismological Laboratory. He wanted to devise a means of assessing them on an objective, quantitative basis. Measuring the amplitudes of seismic waves recorded on seismographs in southern California, Richter formulated a local magnitude scale, to assess the size of earthquakes occurring in the region.

Coal Crimes of Buffalo Creek

Let us imagine that one day a natural disaster hits your town, you watched everyone you know lose their homes, and for some, their lives. Your life view most likely would be skewed for some time, but who could you blame? Nature? God? While tragic, an act of nature or god most often carries no great amount of blame with it. This is not the case in the Buffalo Creek incident however. It is important to note that the people of the Buffalo Creek area were deeply traumatized by this event, and their trust violated by those responsible for this incident. The Buffalo Creek incident is one of the most widely studied disasters in the U. S. and as Kai T. Erikson writes in his prologue to Everything in Its Path â€Å"It was a fairly contained disaster, as such things go, having taken place on a scale small enough to allow one to see it whole,†. There were a number of variables leading into that day, the day the â€Å"dam† gave way, and throughout the course of this paper I intend to trace the pattern back to the source of this disaster, the creator of a situation that certainly does deserve blame. What it comes down to in the aftermath of this disaster is whether to cast the guilt on the coal company that created the environment for this disaster, or the people of the valley who some might say had failed to save themselves. The coal company would trivialize the loss that the people of this valley community had undergone and try to label the flood an â€Å"act of God†. (Stern) I however, soundly took the side of these mountain people as I read about the coal industry’s molestation of their land, and the destruction of WV life as they had once known it. The coal industry creeped its way into the lives of West Virginians over the better part of a century. Although coal had always been rich in West Virginia’s land and it was know for sometime to be that way, coal companies did not gain access to most areas of WV including Logan County until the very early 1900‘s as railroads invaded the hills and valleys. Coal Company employment greatly changed the lives of W. Virginians over time, bringing them down from the mountain farms they used to live on, to factory like homes constructed in crowded valley mining towns. The miners of Logan County were also influenced heavily from the company to remain non-union workers which is to the ultimate benefit of the industry rather than the miner. The popularity of the studies into this disaster are not only beneficial to our response to disasters that are both man made and acts of god, but also to promote the protection and safety of a company’s workers through stricter safety guidelines. On the morning of February 26, 1972 132 million gallons of black water and coal waste forced its way through the impoundments that the Buffalo Mining Company had built in three stages over the span of two or three years. The Pittston Coal Company did not feel they needed to say sorry or offer retribution for the damages caused by their poor management and supervision of dam construction, this act is what sparked the defiance in the people victimized by the flood. (Erikson) Immediately following the disaster Pittston began doing damage control for the protection of the company and tried to place all of the responsibility away from themselves during the ensuing legal battles. Pittston lawyers immediately began treating the people left behind in the wake of the disaster as â€Å"potential adversaries in court action†, questioning them not about the state of their living conditions but instead about their ill will against the company (Erikson). During one of the interviews included in Everything in Its Path a former mine worker said Lawyers had asked him â€Å"Do you have any hard feelings against Pittston? † and â€Å"Do you believe they’ll talk to people? †. While these actions may have seemed like sensible legal maneuvers in Pittston’s legal team, they proved to seed a deep resentment toward the coal company in the minds of Buffalo Creek’s residents. The second mistake Pittston made, as described in The Buffalo Creek Disaster, was them stating that â€Å"the break in the dam was caused by flooding—an Act of God. (Stern). Throughout the works of both Kai T. Erikson and Gerald M. Stern there is a general consensus that the valley community being a largely religious group of people were provoked by this statement. In this respect Pittston ultimately did more to embolden their â€Å"adversaries† than they did to protect themselves from monetary loss in the end. Pittston Coal Company and the Buffalo Mining Company are the responsible parties for this man made disaster from the beginning of it’s creation until the day of the flood. The Buffalo Mining Co. nd Pittston both failed to learn from past mistakes during the construction of the dam system. Pittston ignored the poor quality of the dams built, previous complaints about the lack of emergency run off systems, and multiple previous failures of the dams which were simply patched and reinforced in the same faulty manner as the original was made. In March of 1971 several Coal Company officials noted that there was a significant slumping in dam 3 and it was estimated at â€Å"150 to 200 feet wide across the face of the dam and 20 to 30 feet from the face back. by testimony of Ben Tudor, General Superintendent, Buffalo Mining Company. Later that same month it was recorded that a West Virginia Department of Natural Resources inspector had listed a â€Å" â€Å". . . lack of emergency s pillway or overflow system from upper impoundment. † (In this instance, â€Å"upper impoundment† refers to Dam No. 3. )†. Despite these and many other alarming findings, no significant improvements were made before the dam system’s failure in 1972. (Kelley). On the day of the disaster, citizens of Buffalo Creek Valley had little or no warning from Pittston or the Buffalo Mining Co. f the impending danger until the wall of water had descended upon them. â€Å"Pittston Coal neglected to warn The Mining Bureau, the National Guard, the State Police, and even the Logan County Sheriff’s office. † (Stern). In Everything in Its Path Erikson includes several accounts of victims who had been given no warning at all that there was danger of a flood at that time. The importance of this disaster and its aftermath has permanently touched the way we handle disaster prevention, relief, post traumatic counseling, and hopefully future litigation. While the magnifying glass initially was held over the coal industry and specifically on the legal battle that the people of Buffalo Creek eventually would win, its scope has continued to broaden over years and will remain an important learning tool for use in varieties of disasters on the earth and humanity. Consider the lessons to be learned by all companies and corporations in respect to how they monitor the safety of their employees and the communities they have potential impact on. I ask you to consider the victims of the Buffalo Creek flood as brave pioneers into the world of disasters, and appreciate the advancements that have been made possible by their bravery.

Kennedy was a phenomenal speaker. He knew how to use his words to rally support from his audience. Don’t waste time! Our writers will create an original "Analysis of John F. Kennedy Inaugural Speech" essay for you Create order Therefore, he was not an inspirational leader and through his words he was able to move his audience. President Kennedy was able to reach out to his audience by addressing their emotions and their beliefs. Throughout his speech, President Kennedy use various literary devices to connect with his audience and to persuade them to see that they did not just make a huge mistake by electing him as their president. He was a man for the people of this great nation. In the first few paragraphs, President Kennedy ceremoniously used ethos to captive his total audience and to rally them as one by first addressing all those in attendance saying, Vice President Johnson, Mr. Speaker, Mr. Chief Justice, President Eisenhower, Vice President Nixon, President Truman, Reverend Clergy, fellow citizens: In addition, he appealed to his audience by referencing the almighty god. He says, For I have sworn before you and almighty God the same solemn oath ., and as history tells us this nation was based built and founded on religious beliefs and freedom. Furthermore, President Kennedy continued to say that the beliefs that the right of man come not from the generosity of the state but by the hand of God. He appeals to the audiences religious ideologies. President Kennedy used strong sentences and words to inspire his audience and to show that we as a people are mighty as a team and weak as individuals. For this he uses the literacy device parallelism to show the two opposites, strong versus weak. He tells the audience that united, there is little that we cannot do in a host of cooperative ventures. Divided, there is little we can do-for we dare not meet a powerful challenge at odds and split asunder. Another use of parallelism was Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty. We can make a difference as long as we stand together. He emphasizes the word, we. Another example of parallelism in President Kennedys speech was when he said, We shall not always expect to find them supporting our view. But we shall always hope to find them strongly supporting their own freedom and t o remember that, in the past, those who foolishly sought power by riding the back of the tiger ended up inside. In his speech he addresses the emotional side (pathos) of his audience to propel patriotism by saying, So let us begin anew remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Also he showed the importance of a team by using the word, us. President Kennedy wanted to show that he does not stand by himself but with the people. Also, he repeats the word, us in saying Let us never negotiate out of fear. But let us never fear to negotiate. He was saying that as a people we move forward in our endeavors that we do it without fear, but with perseverance and a sound mind. In addition, he acknowledge that freedom was obtained by not just remembering the old but also the young. For by The graves of young Americans who answered the call of service surround the globe, we as a nation enjoy freedom. Once again, he enticed everyone in his speech and not just giving credit to the old but recognized that if it was not for the young soldiers tha t fought and sacrificed their lives we would not be free. But also, he wanted the people to know that it was going to take everyone working together to sustain what we have come to love and enjoy, our rights and our freedom to execute our rights. Moreover, not only did President Kennedy use the literacy devices pathos and ethos, but he eloquently used logos. At the very beginning of his speech after addressing the people in his audience. He said, The world is very different now. Truth to be told, it was. The world was wiser in the sense that man had made advancement in science and technology. He said, For man holds in his mortal hands the power to abolish all forms of human poverty and all forms of human life. Man knew how to create life as well as destroy it. Also, he said. In your hands, my fellow citizens, more than mine, will rest the final success or failure of our course. As president he would sign the executive order to go to war, but he would not be on the battle field fighting physically. So, the success or failure of this country actually rests on the shoulders of the citizens of this country. The citizens of this country bear the burdens of war and what it entails the good and the bad effects of war. If we as the c itizens of this great country want freedom to remain and to exist, then it is up to the citizens of this country. In John F. Kennedys inaugural speech, he employed so many literacy devices. Besides ethos, logos, and pathos, he used alliteration as well as metaphor. Phrases from his speech such as same solemn, man holds in his mortal hands, and pay any price, bear any burden, and let us go forth to lead the land we love are just a few alliterations he used in his speech to help persuade his audience to support him as the president of the United States of America. The metaphor he stated made reference to areas being poor or improvised. He said, To assist free men and free governments in casting off the chains of poverty. This metaphor was appealing to their human side. There was work to be done in this world, but it would not get done by himself just saying it or by him alone. It was going to take the people to make the change and in this case to end poverty. As President Kennedy comes to an end he impels the importance of citizenship and what we can and should do for our country. Once again, the words, we and our indicate that he is not talking as one but for many, and it is not about him. Although he is president of the United States, he recognized that this country belonged to the people, and he was only a vessel to ensure that the rights of all are addressed and upheld. Furthermore, he said with a good conscience our only sure reward, with history . is knowing that here on earth Gods work must be truly be our own. People in this world have a Christian duty, and that is to do the will of God. He once again appeal to their moral stance. In addition, President Kennedy is known for his famous line ask not what your country can do for you ask what you can do for your country. Once again, he places the responsibility of this country growing, succeeding, flourishing, and being free upon the shoulders of the citizens of this country.
