Question 559199
Determine the critical region and critical values for z that would be used to test the null hypothesis at the given level of significance, as described in each of the following: 

(A) Ho: u &#8805; 53 and Ha: u <53, a = 0.01
z = invNorm(0.01) = -2.3263
----------------------------------------

(B) Ho: u &#8804; 32 and Ha: u > 32, a = 0.05
z = invNorm(0.95) = 1.645
--------------------------------------------

(C) Ho: u = 24 and , Ha: u &#8800; 24 a = 0.10
z< -1.645 or z> +1.645
