Question

A group of researchers developed a new method for ranking the total driving performanoe of golfers on a tour. The method requires knowing a golfer's average driving distance (yards) and driving accuracy (peroent of drives that land in the fairway). They construct a straight-line model relating driving accuracy (y) to driving distance(x). A MINITAB printout with prediction and confidenoe intervals for a driving distanoe of x-300 is shown below Click the icon to view the table and the MINITAB output. a. Locate the 95% prediction interval for driving eccuracy (y) on the printout, and give a practical interpretation of the result The 95% prediction interval is( (Round to three decimal plaoes as needed.) Give a practical interpretation of the result. Choose the correct answer below A. We are 95% confident that the actual driving accuracy for a golfer driving the ball 300 yards is between the limits of the prediction interval 0 B. There is not enough information to answer this question. Data Table MINITAB output Predicted Values For New Observations New Obs Fit C. we are 95% confident that the mean driving accuracy for all golfers driving the ball 300 yards is between the limits of the prediction interval b. Locate the 95% confidence interval for mean driving accuracy (y) on the printout, and give a practical interpretation of the result. The 95% confidence interval is Round to three decimal places as needed.) Give a practical interpretation of the result.

We are 95% confident that the mean driving accuracy for all golfers driving the ball 300 yards is between the limits of the confidence interval c. If you are interested in knowing the average driving accuracy of all golfers who have a driving distanoe of 300 yards, which of the intervals is relevant? Explain. Choose the correct answer below A. 0 B. O C. The confidence interval for the mean because it estimates the mean while the prediction interval for the actual value estimates a single value, not a mean. There is not enough information to answer this question. The prediction interval for the single value because it estimates the single value while the confidenoe interval for the mean estimates the mean
