Using the information in Example 7.3, plot the probability of Type II error as a function of . How does this compare with Figure 7.2?

We find the area under the curve to the left of the critical value (the nonrejection region) for each of these values of the true mean. That would be the probability of not rejecting the null hypothesis.

Note that the variable beta contains the probability of Type II error (the area to the left of the critical value ctv under a normal curve with mean mualt and standard deviation sig) for every . To get the power, simply subtract all of the values for beta from one.
