Recall that the method incorporates a golfer's average driving distance (yards) and driving accuracy (percent of drives that land in the fairway) into a driving performance index. Data on these three variables for the top 40 PGA golfers are saved in the accompanying file. Determine which of these variables-driving distance, driving accuracy, and driving performance index-are approximately normally distributed.
For Information: Refer to The Sport Journal (Winter 2007) article on a new method for ranking the driving performance of PGA golfers, Exercise 2.50.
