The following MINITAB output presents the

Chapter 6, Problem 10E

(choose chapter or problem)

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

b. Assume that the value of $\mu$ used for the null hypothesis is $\mu=3$. For what alternate value of $\mu$ is the power calculated?

c. If the sample size were 25, would the power be less than 0.85, greater than 0.85, or is it impossible to tell from the output? Explain.

d. If the difference were 0.5, would the power be less than 0.90, greater than 0.90, or is it impossible to tell from the output? Explain.

e. If the sample size were 17, would the power be less than 0.85, greater than 0.85, or is it impossible to tell from the output? Explain.
