The following data give information on the average ticket prices (in U.S. dollars) and the average percentage of capacity filled for seven hockey teams during the 2011€“2012 National Hockey League regular season. (Capacity levels exceeding 100.0% imply standing-room-only attendees.)

a. Taking average ticket price as an independent variable and percentage of capacity filled as a dependent variable, compute SSxx, SSyy, and SSxy.
b. Find the least squares regression line.
c. Briefly explain the meaning of the values of a and b calculated in part b.
d. Calculate r and r2 and briefly explain what they mean.
e. Compute the standard deviation of errors.
f. Construct a 95% confidence interval for B.
g. Test at a 2.5% significance level whether B is positive.
h. Using a 2.5% significance level, test whether p is positive.
