Based on this information, answer the questions below.

A union of restaurant and foodservice workers would like to estimate this year's mean hourly wage, u, 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 different from last year's. The union decides to do a statistical test to see if the value has indeed changed. The union chooses a random sample of this year's wages, computes the mean of the sample to be $7.77, and computes the standard deviation of the sample to be $1.20. 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: His ? ? H : u is ? C ? E In the context of this test, what is a Type II error? A Type II error is (? the hypothesis that u is (? @ ? when, in fact, u is ? @ ? Suppose that the union decides not to reject the null hypothesis. What sort of error might it be making
