Beer Consumption. The null and alternative hypotheses for the hypothesis test in Problem 26 are, respectively, H0: μ = 22 gallon (mean has not increased)

Ha: μ > 22 gallon (mean has increased), where μ is last year’s mean beer consumption for all Americans. Explain what each of the following would mean.

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 beer consumption

d. has not increased from the 2010 mean of 22 gallon.

e. has increased from the 2010 mean of 22 gallon.
