A union of restaurant and foodservice workers would like to estimate this year's mean hourly wage, , of foodservice workers in the U.S. Last year's mean hourly wage was $8.14, and there is reason to believe that this year's value is greater than last year's. The union decides to do a statistical test to see if the value has indeed increased. The union chooses a random sample of this year's wages, computes the mean of the sample to be $8.44, and computes the standard deviation of the sample to be $1.10. Based on this information, answer the questions below. What are the null hypothesis (H) and the alternative hypothesis (H,) that should be used for the test? H: u is ? H: p is ? ? In the context of this test, what is a Type I error? A Type I error is ? v the hypothesis that u is ? when, in fact, is ? Suppose that the union decides to reject the null hypothesis. What sort of error might it be making?
