# Question: The null and alternative hypotheses for the hypothesis test in

The null and alternative hypotheses for the hypothesis test in Problem 24 are, respectively,

H0: μ = 30.0 lb (mean has not increased)

Ha: μ > 30.0 lb (mean has increased), where μ is last year's mean cheese consumption for all Americans.

Explain what each of the following would mean.

a. Type I error

b. Type II error

c. Correct decision

Now suppose that the results of carrying out the hypothesis test lead to rejection of the null hypothesis. Classify that decision by error type or as a correct decision if in fact last year's mean cheese consumption

d. Has not increased from the 2001 mean of 30.0 lb.

e. Has increased from the 2001 mean of 30.0 lb.

H0: μ = 30.0 lb (mean has not increased)

Ha: μ > 30.0 lb (mean has increased), where μ is last year's mean cheese consumption for all Americans.

Explain what each of the following would mean.

a. Type I error

b. Type II error

c. Correct decision

Now suppose that the results of carrying out the hypothesis test lead to rejection of the null hypothesis. Classify that decision by error type or as a correct decision if in fact last year's mean cheese consumption

d. Has not increased from the 2001 mean of 30.0 lb.

e. Has increased from the 2001 mean of 30.0 lb.
