Floretta, a gym owner, claims that her yearly new customers are more than 163 people, on average. Several of her friends do not believe her, so she decides to do a hypothesis test, at a 1% significance level, to persuade them. She collects data from 25 previous years and works through the testing procedure: 167 ·α = 0.01 (significance level) The test statistic is 167 163 - 1.82 The critical value is z0.o1 2.33. Conclude whether to reject or not reject Ho, and interpret the results.
