Question:

Refer to the Baseball 2010 data, which report information on the 30 Major League Baseball teams for the 2010 season.

a. 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 season as having won 81 or more games. Next, find the median team payroll and divide the teams into two payroll groups. Let the 15 teams with the largest payrolls be in one group and the 15 teams with the smallest payrolls be in the other. At the .05 significance level, is there a relationship between payrolls and winning?

b. Use a statistical software program to determine whether the variables payroll and attendance follow a normal distribution. Use the .05 significance level.
