Hole in One ~ Shelyce is very interested in professional golf statistics. She obtains data from 2008 for the highest earning professional golfers that year. The data set contains the variables: 1) Drive Accuracy (in percentage): the percentage of time a tee shot comes to rest in the fairway. 2) Drive Distance (in yards): the average distance a golfer hits the golf ball using the driver. 3) Greens in Regulation (in percentage): the percentage of time a ball is on the putting surface after a Greens in Regulation stroke. Shelyce wants to use linear regression to predict a pro golfer’s Drive Accuracy. The scatter plots and summary statistics below summarize the data for 150 professional golfers in 2008.

Question

Hole in One ~ Shelyce is very interested in professional golf statistics. She obtains data from 2008 for the highest earning professional golfers that year. The data set contains the variables:

1) Drive Accuracy (in percentage): the percentage of time a tee shot comes to rest in the fairway.

2) Drive Distance (in yards): the average distance a golfer hits the golf ball using the driver.

3) Greens in Regulation (in percentage): the percentage of time a ball is on the putting surface after a Greens in Regulation stroke.

Shelyce wants to use linear regression to predict a pro golfer’s Drive Accuracy. The scatter plots and summary statistics below summarize the data for 150 professional golfers in 2008.
