A group of Northeastern University researchers developed a new method for ranking the total driving performance of golfers on the Professional Golf Association (PGA) tour (Sport Journal, Winter 2007). The method requires knowing a golfer's average driving distance (yards) and driving accuracy (percent of drives that land in the fairway). The values of these two variables are used to compute a driving performance index. Data for a random sample of 40 PGA golfers are available in the Excel tab named Q1 PGADRIVER. A professional golfer is practicing his swing to increase his average driving distance. However, he is concerned that his driving accuracy will be lower. Is his concern a valid one? Use simple linear regression, where y = driving accuracy and x = driving distance, to answer the question.
