Explanation / Answer

Result:

a).

95% prediction interval is (56.718, 65.892)

B.) 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.

b).

95% confidence interval is (60.574, 62.036)

B.) 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).

A.). 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.
