Suppose a golfer claims that her drive distance is more than 162 meters, on average. Several of her friends do not believe her, so the golfer decides to do a hypothesis test, at a 1% significance level, to persuade them. She hits 13 drives. The mean distance of the sample drives is 187 meters. The golfer knows from experience that the standard deviation for her drive distance is 21 meters. • Ho: 4 = 162; H,:H > 162 a = 0.01 (significance level) What is the test statistic (z-score) of this one-mean hypothesis test? Select the correct answer below: 4.29 + 4.12 * -4.29 * -4.12
