For the punter data in Case Study 12.2, an additional response, “punting distance,” was also recorded. The average distance values for each of the 13 punters are given.

1. Using the distance data rather than the hang times, estimate a multiple linear regression model of the type for predicting punting distance.

2. Use stepwise regression with a significance level of 0.10 to select a combination of variables.

3. Generate values for s , R , PRESS, and for the entire set of 31 models. Use this information to determine the best combination of variables for predicting punting distance.

2 2 4. For the final model you choose, plot the standardized residuals against Y and do a normal probability plot of the ordinary residuals. Comment.
