Power. In Exercise 15.41, a sample from a Normal population with mean μ = 10 APPLET ••• and standard deviation σ = 2 failed to reject the null hypothesis H0: μ = 8 at the

α = 0.05 significance level. Enter the information from this example into the Power of a Test applet. (Don’t forget that the alternative hypothesis is two-sided.) What is the power of the test against the alternative μ = 10? Because the power is not high, it isn’t surprising that the sample in Exercise 15.41 failed to reject H0.
