The following regression model was fitted to data on 60 U.S. female amateur golfers:

yn = 164,683 + 341.10x1 + 170.02x2 + 495.19x3 - 4.23x4 1100.592 1167.182 1305.482 190.02

-136,040x5 - 35,549x6 + 202.52x7 125.6342 116, 2402 1106.202 R2 = .516 where yn = winnings per tournament in dollars x1 = average length of drive in yards x2 = percentage times drive ends in fairway x3 = percentage times green reached in regulation x4 = percentage times par saved after hitting into sand trap x5 = average number of putts taken on greens reached in regulation x6 = average number of putts taken on greens not reached in regulation x7 = number of years the golfer has played The numbers in parentheses under the coefficients are the estimated coefficient standard errors.
Write a report summarizing what can be learned from these results.
The following exercises use a data set and require a statistical computer package to prepare the regression analysis for the problem solution.
