"Tiger Woods uses Titleist brand golf clubs" the salesperson says to me. He promises me that my game will improve if I buy the expensive Titleist clubs which are, after all, endorsed by Tiger. But I am a smart consumer, and rather than wasting money on expensive clubs, I first want to know if they work. So, I borrow the Titleist clubs and have 5 randomly selected golfers use them, recording their scores. I also have 6 other randomly selected golfers use my old clubs. Using the data below and the steps of hypothesis testing, test the salesperson's claim that the Titleist clubs will produce a lower score than my clubs (lower is better). Set a = .05. (Note that the scores and scores-squared have already been summed for you at the bottom. Titleist (X) 92 X² 8464 Old Clubs (Y) 104 y² 10816
