# Question

The data from Exercise 4.64 for number of birdies during a tournament and final score for 63 women golfers are on the WeissStats CD.

In exercise

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 OpenWeb site, we obtained data on number of birdies during a tournament and final score for 63 women golfers. The data are presented on the WeissStats CD.

a. Decide whether use of the linear correlation coefficient as a descriptive measure for the data is appropriate. If so, then also do parts (b) and (c).

b. Obtain the linear correlation coefficient.

c. Interpret the value of r in terms of the linear relationship between the two variables in question.
