Data Set Exercise – Each Data Set Exercise is worth 20 pointsUse the Data Sets found in Appendix A in the back of your book to complete the following exercises.1. Refer to the Baseball 2012 data, which reports information on the 2012 Major League Baseball season. Let attendance be the dependent variable and total team salary, in millions of dollars, be the independent variable. Determine the regression equation and answer the following questions. a. Draw a scatter diagram. From the diagram, does there seem to be a direct relationship between the two variables? b. What is the expected attendance for a team with a salary of $80.0 million? c. If the owners pay an additional $30 million, how many more people could they expect to attend? d. At the .05 significance level, can we conclude that the slope of the regression line is positive? Conduct the appropriate test of hypothesis. e. What percentage of the variation in attendance is accounted for by salary? f. Determine the correlation between attendance and team batting average and between attendance and team ERA. Which is stronger? Conduct an appropriate test of hypothesis for each set of variables.2. Refer to the Baseball 2012 data, which report information on the 30 Major League Baseball teams for the 2012 season. Let the number of games won be the dependent variable and the following variables be independent variables: team batting average, number of stolen bases, number of errors committed, team ERA, number of home runs, and whether the team plays in the American or the National League. a. Use a statistical software package to determine the multiple regression equation. Discuss each of the variables. For example, are you surprised that the regression coefficient for ERA is negative? Is the number of wins affected by whether the team plays in the National or the American League? b. Find the coefficient of determination for this set of independent variables. c. Develop a correlation matrix. Which independent variables have strong or weak correlations with the dependent variable? Do you see any problems with multicollinearity? d. Conduct a global test on the set of independent variables. Interpret. e. Conduct a test of hypothesis on each of the independent variables. Would you consider deleting any of the variables? If so, which ones? f. Rerun the analysis until only significant regression coefficients remain in the analysis. Identify these variables. g. Develop a histogram or a stem-and-leaf display of the residuals from the final regression equation developed in part (f). Is it reasonable to conclude that the normality assumption has been met? h. Plot the residuals against the fitted values from the final regression equation developed in part (f). Plot the residuals on the vertical axis and the fitted values on the horizontal axis.3. Refer to the Buena School District bus data. First, add a variable to change the type of bus (diesel or gasoline) to a qualitative variable. If the bus type is diesel, then set the qualitative variable to 0. If the bus type is gasoline, then set the qualitative variable to 1. Develop a regression equation using statistical software with maintenance as the dependent variable and age, miles, and bus type as the independent variables. a. Write out the multiple regression equation analysis. Discuss each of the variables. b. Determine the value of R2. Interpret. c. Develop a correlation matrix. Which independent variables have strong or weak correlations with the dependent variable? Do you see any problems with multicollinearity? d. Conduct the global test on the set of independent variables. Interpret. e. Conduct a test of hypothesis on each of the independent variables. Would you consider deleting any of the variables? If so, which ones? f. Rerun the analysis until only significant regression coefficients remain in the analysis. Identify these variables. g. Develop a histogram or a stem-and-leaf display of the residuals from the final regression equation developed in part (f). Is it reasonable to conclude that the normality assumption has been met? h. Plot the residuals against the fitted values from the final regression equation developed in part (f) against the fitted values of Y. Plot the residuals on the vertical axis and the fit-ted values on the horizontal axis.The software that is recommended to complete these exercises is MegaStat for Microsoft Excel.

Martin Luther King’s Last Speech Essay
Introduction “I have been to the mountain” was Martin Luther King’s last speech before he was assassinated. In this speech, King aims at maintaining action by encouraging the civil rights activists to continue fighting for racial equality. He uses biblical references to pass his message across to the people. He says that just like the biblical Jews who suffered in the wilderness, but their descendants finally reached the Promised Land, so will the descendants of the black people in the United States. King rallies the people to keep fighting for their rights and never to give up. He refers to the many successes the movements have had so far. He realized that this was the best tactic to encourage the people to make sure that disillusionment does not overwhelm idealism. He compared past events and to make conclusions that all will be well in the future. On most occasions he uses the bible, for instance, he compares the Jews slaves who were persecuted in Egypt, but due to their perseverance, they lived until they were released and eventually reached the Promised Land, to the black slaves in America whom he believed would also finally be free. This was his central claim, which actually comes out clearly in this line “I want you to know tonight that we as a people will get to the Promised Land” (King 1). This served to encourage the civil rights activists to employ righteousness in their fight for equality. In this speech King was speaking directly to the sanitation workers who were striking in Memphis, but his intention was to reach all African Americans to encourage them to rally behind the movement so that they can achieve their civil rights. He uses many past events to support this claim. For instance, he uses past efforts to illustrate some of the civil rights successes. Among them are the sit-ins that happened in North Carolina, the freedom rides that were witnessed in the South, the Negro activism in states like Georgia, Albany, Alabama, and Birmingham, and also the many supporters who trooped to capital in 1963 to participate in the demonstration in which King gave his “I have a dream” speech. He also used those fighting injustice in Memphis, Alabama, and Selma to support his claim (King 1). King uses his oratory skills in this speech to create a role of activist to be played by his audience by retelling heroism stories in the past and assuring them that they will eventually succeed even without him around. He employs a superior relationship with the audience by using many personal examples in supporting his claim. This made the people realize that he was a very important person to them. The role of prophet that he gives himself makes people believe in every word that come out of his mouth. Get your 100% original paper on any topic done in as little as 3 hours Learn More When he says “I want to thank God once more for allowing me to be here with you” (King 1), he brings out the idea that he is chosen by God to deliver his people from misery. He uses near death experiences that he has gone through to paint himself as a person who has been tested and chosen. He also emerges as a visionary when he claims that he has been on the top of the mountain and has seen the Promised Land (King 1). King uses a well organized chronological structure that he strategically embeds in the context of the time. He travels back to refer to the early successes of the movement in the start of the 1960s and works his way systematically to the present and concludes the speech with a visionary look into the future ahead. By using this structure, King was able to rekindle enthusiasm in his audience by reminding them of their circumstances and encouraging them to always keep in mind their current troubles (King 1). In short, King claims that the efforts of the civil rights movement will come to bear fruit. He proves this by sharing his dream with the people. Having assumed a prophetic figure, he did not need much proof to strengthen his message although he has cited a few. His message was a humble plea for equality not a demand by blacks that could create fear in the white population. This is shown by his contrasting example of the black women who attempted to kill him and that of the small white girl who admired him. Work Cited King Martin. “I’ve Been to the Mountaintop”.
