Refer to the Baseball 2016 data, which report information on the 30 Major League

Baseball teams for the 2016 season.

a. At the .05 significance level, can we conclude that there is a difference in the mean

salary of teams in the American League versus teams in the National League?

b. At the .05 significance level, can we conclude that there is a difference in the mean

home attendance of teams in the American League versus teams in the National

League?

c. Compute the mean and the standard deviation of the number of wins for the

10 teams with the highest salaries. Do the same for the 10 teams with the lowest

salaries. At the .05 significance level, is there a difference in the mean number of

wins for the two groups? At the .05 significance level, is there a difference in the

mean attendance for the two groups?
