The Ladies Professional Golfers Association (LPGA) maintains
statistics on performance and earnings for members of the LPGA
Tour. Year-end performance statistics for 30 golfers for 2014
appear in the file named 2014LPGAStats (LPGA website, April 2015).
Earnings ($1000s) is the total earnings in thousands of dollars;
Scoring Avg. is the scoring average for all events; Greens in Reg.
is the percentage of time a player is able to hit the greens in
regulation; and Putting Avg. is the average number of putts taken
on greens hit in regulation. A green is considered hit in
regulation if any part of the ball is touching the putting surface
and the difference between par for the hole and the number of
strokes taken to hit the green is at least 2.
a. Develop an estimated regression
equation that can be used to predict the average score for all
events given the percentage of time a player is able to hit the
green in regulation and the average number of putts taken on greens
hit in regulation (to 4 decimal). If required enter negative values
as negative numbers.
Scoring Avg. = + Greens in
Reg. + Putting Avg.
