Serious golfers and golf equipment companies sometimes make use of golf equipment testing labs to obtain precise information about particular club heads, club shafts, and golf balls. One golfer requested information about the Jazz Fat Cat 5-iron from Golf Laboratories, Inc. The company tested the club by using a robot to hit a Titleist NXT Tour ball six times with a head velocity of 85 miles per hour. The golfer wanted a club that, on average, would hit the ball more than 180 yards at the club speed. The six different tries with the club resulted in a mean distance of 182.7 yards and a standard deviation of 2.7 yards. At the 5% significance level, does the data support what the golfer wants out of a club? Is this a 2-score or a t-score problem? Ho H HAP yards yards Is this right-tailed, left tailed, or two-tailed test? Test statistic Critical value OR P-value Decision Conclusion: There is evidence to the claim that the average distance with the club will be more than 180 yards
