1. Refer to the baseball data for 2005 on 30 major league teams (see bottom of page). Use a Contingency Table to analyze the relationship between games won and salary. Set up a variable that divides the teams into two groups, those that had a winning season and those that did not. There are 162 games in the season, so define a winning team as having won 82 or more games. Next, divide the teams into two salary groups. Let the 15 teams with the largest salaries be in one group and the 15 teams with the smallest salaries in the other group. At the .05 level of significance is there a relationship between salary and winning?

B. Use Spearman's Rank-Order Correlation method to compute the coefficient of correlation between salary and the number of wins. Test the significance of this correlation using the t-test. At the .05 and .01 level of significance, is there a relationship between salary and winning?

C. Use linear regression analysis to compute the correlation between Wins and Salary. List the regression equation, and all associated regression output. At the .05 and .01 level of significance, is there a relationship between salary and winning?
