The LPGA has gathered data on it's golfers and would like to be able topredict earnings for players based on their performance. For each golfer in the LPGA, they have gathered their Earning ($), Scoring Avg., Greens in Reg., and Putting Avg. Sample data is shown below. They have developed 4 different regression models to predict Earning ($) and want to be sure that they only include independent variables in the model that have a coefficient that is not statistically equal to zero using = 0.05. (Specifically that for any of the variables).
Player | Earnings ($) | Scoring Avg. | Greens in Reg. | Putting Avg. |
Annika Sorenstam | 2,588,240 | 69.33 | 0.772 | 1.75 |
Paula Creamer | 1,531,780 | 70.98 | 0.727 | 1.75 |
Cristie Kerr | 1,360,941 | 70.86 | 0.722 | 1.76 |

Natalie Gulbis | 1,010,154 | 71.24 | 0.709 | 1.78 |
