Let $\mu$ denote the true average number of minutes of a television commercial. Suppose the hypotheses are tested. Assuming the commercial time is normally distributed, give the appropriate rejection region for each of the following sample sizes and significance levels.
a. n = 6, = 0.01
b. n = 12, = 0.05
c. n = 20, = 0.05
d. n = 23, = 0.1
