Refer to Exercise 14. A test of the hypotheses H0: = 1 versus H1:

Refer to Exercise 14.

A test of the hypotheses H0: μ = 1 versus H1: μ ≠ 1 will be made at the

α = 0.01 level of significance. Assume that the population standard deviation is σ = 0.2 and that the sample size is n = 314.

Find the power of the test against the alternative

μ1 = 0.98.

Exercise 14

An article in the International Journal of Clinical Practice described a study in which a sample of 314 patients took a combination of the drugs ezetimibe and simvastatin in order to reduce their total blood cholesterol levels. A test of the hypotheses H0: μ = 1 versus H1: μ > 1 will be made at the α = 0.05 level of significance.

Assume the population standard deviation is σ = 0.2.
