Consider again the regression of Average Attendance on Wins for the baseball teams examined in Exercise 44.

Dependent variable is Home Attendance

R-squared = 6.45%

Variable                     Coefficient

Intercept ………...          16484.0

Wins ……….........                147.4

a) What is the correlation between Wins and Average Attendance?

b) What would you predict about the Average Attendance for a team that is 2 standard deviations above average in Wins?

c) If a team is I standard deviation below average in attendance, what would you predict about the number of games the team has won?
