A union of restaurant and foodservice workers would like to estimate the mean hourly wage, μ, of foodservice workers in the U.S. this year The mean hourly wage last year was $8.16, and there is good 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 $8.43, and computes the standard deviation of the sample to be $1.25. Based on this information, complete the parts below. Suppose the true mean hourly wage for foodservice workers in the U.S. this year is $8.16. Fill in the blanks to describe a Type I error. 1. A Type I error would be (rejecting) or (failing to reject) the hypothesis 2. That μ is (less than) (less than or = to) (greater than) (greater than or = to) (not = to) or (= to) 3. The number (1.25), (8.43), or (8.16) 4. When, in fact, μ is (= to 1.25) (= to 8.43) (= to 8.16) (not = to 8.16) (less than 1.25) (greater than 8.43)
