The following data give information on the average ticket prices

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.
