Exercises contain graphs portraying the decision criterion for a one-mean z-test. The curve in each graph is the normal curve for the test statistic under the assumption that the null hypothesis is true. For each exercise, determine the

a. rejection region.

b. nonrejection region.

c. critical value(s).

d. significance level.

e. Construct a graph similar to that in Fig on page 378 that depicts your results from parts (a)–(d).

f. Identify the hypothesis test as two tailed, left tailed, or right tailed.
