Refer to The Sport Journal (Winter 2007) study of a new method for ranking the total driving performance of golfers on the Professional Golf Association (PGA) tour, presented in Exercise. You fit a straight-line model relating diving accuracy (y) to driving distance (x) to the data saved in the PGADRIVER file. A MINITAB printout with prediction and confidence intervals for a driving distance of x = 300 yards is shown below.
a. Locate the 95% prediction interval for driving accuracy (y) on the printout, and give a practical interpretation of the result.
b. Locate the 95% prediction interval for mean driving accuracy (y) on the printout, and give a practical interpretation of the result.
c. If you are interested in knowing the average driving accuracy of all PGA golfers who have a driving distance of 300 yards, which of the intervals is relevant? Explain.
