Consider the golf ball overall distance data in Exercise 6-25.
(a) Do these data support the claim that the mean overall distance for this brand of ball does not exceed 270 yards? Use a = 0.05.
(b) What is the P-value for the test in part (a)?
(c) Do these data appear to be well modeled by a normal distribution? Use a formal goodness-of-fit test in answering this question.
