Problem 9E

The following MINITAB output presents the results of a power calculation for a test concerning a population proportion p.

a. Is the power calculated for a one-tailed or two-tailed test?

b. What is the null hypothesis for which the power is calculated?

c. For what alternative value of p is the power calculated?

d. If the sample size were 100, would the power be less than 0.7, greater than 0.7, or is it impossible to tell from the output? Explain.

e. If the sample size were 200, would the power be less than 0.6, greater than 0.6, or is it impossible to tell from the output? Explain.

f. For a sample size of 150, is the power against the alternative p = 0.3 less than 0.65, greater than 0.65, or is it impossible to tell from the output? Explain.

g. For a sample size of 150, is the power against the alternative p = 0.45 less than 0.65, greater than 0.65, or is it impossible to tell from the output? Explain.
