b. Obtain the coefficient of determination.

c. Determine the percentage of variation in the observed values of the response variable explained by the regression, and interpret your answer.

Exercise 4.70

How important are birdies (a score of one under par on a given golf hole) in determining the final total score of a woman golfer? From the U.S. Women’s Open website, we obtained data on number of birdies during a tournament and final score for 63 women golfers. The data are presented on the WeissStats site.
