Textbook Question
Chapter 16.2, Problem 13E
Refer to exercise 12.
- a. Develop an estimated regression equation that can be used to predict the total earnings for all
events given the average number of putts taken on greens hit in regulation. - b. Develop an estimated regression equation that can be used to predict the total earnings for all events given the average number of putts taken on greens hit in regulation, the percentage of time a player is able to hit the greens in regulation, and the percentage of times a player’s tee shot comes to rest in the fairway.
- c. At the .05 level of significance, test whether the two independent variables added in part (b), the percentage of time a player is able to hit the greens in regulation and the percentage of times a player’s tee shot comes to rest in the fairway, contribute significantly to the estimated regression equation developed in part (a). Explain.
- d. In general, lower scores should lead to higher earnings. To investigate this option for predicting total earnings, develop an estimated regression equation that can be used to predict total earnings for all events given the average score for all events. Would you prefer to use this equation to predict total earnings, or would you prefer to use the estimated regression equation developed in part (b)? Explain.
