Problem #2
Nike claims that golfers can lower their scores by using their newly designed golf clubs.
Eight golfers are randomly selected and each is asked to give his or her most recent score.
After using the new clubs for one month, the golfers are again asked to give their most
recent scores. (Assume for this problem that golfers will tell the truth!) The scores for
each golfer are given in the table below. Assuming the golf scores are normally
distributed, is there enough evidence to support Nike's claim at a = 0.05?
