Essay

Let the test statistic Z have a standard normal distribution when $H _ { 0 }$ is true. Give the significance level for each of the following situations.
a. $H _ { ± } : \mu > \mu _ { 1 } , \text { rejection region } z \geq 2.602$ b. $H _ { \pm } : \mu < \mu _ { 0 } , \text { rejection region } z \leq - 2.069$ c. $H _ { \pm } : \mu = \mu _ { 0 } \text {, rejection region } z \geq 2.042 \text { or } z \leq 2.042$
