Question 9 of 24 Step 4 of 5 02:08:40 A golf club manufacturer claims that golfers can lower their scores by using the manufacturer's 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 asked again to give their most recent score. The scores for each golfer are given in the table below. Is there enough evidence to...

Question 9 (1 point) The owner of a golf course wants to determine if his golf course is more difficult than the one his friend owns. He has 10 golfers play a round of 18 holes on his golf course and records their scores. Later that week, he has the same 10 golfers play a round of golf on his friend's course and records their scores again. The average! difference in the scores (treated as the scores on his course...
