A union of restaurant and foodservice workers would like to estimate the mean hourly wage,

, 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 less than last year's.

The union decides to do a statistical test to see if the value has indeed decreased. The union chooses a random sample of this year's wages, computes the mean of the sample to be

$7.79

, and computes the standard deviation of the sample to be

$1.10

.

Based on this information, complete the parts below.

(a)	What are the null hypothesis H0 and the alternative hypothesis H1 that should be used for the test?
H0:
H1:
(b)	Suppose that the union decides to reject the null hypothesis. What sort of error might it be making?
	(Choose one)
(c)	Suppose the true mean hourly wage for foodservice workers in the U.S. this year is $7.74 . Fill in the blanks to describe a Type II error.
A Type II error would be (Choose one) the hypothesis that is (Choose one) (Choose one) when, in fact, is (Choose one) .
