Essay

Let the test statistic T have a t distribution when $H _ { 0 }$ is true. Give the significance level for each of the following situations:
a. $H _ {\pm } : \mu > \mu _ { 0 } , d f = 15 , \text { rejection regiont } \geq 3.733$ b. $H _ { \pm } : \mu < \mu _ { 0 } , n = 24 , \text { rejection region } t \leq - 2.500$ c. $H _ { \pm } : \mu \neq \mu _ { 1 } , n = 31 \text {, rejection region } t \geq 31.697 \text { or } t \leq - 1.697$
