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)hou = 71 hau= 71 = null = 0.05
Ho: u = 71
Ha: u # 71
alpha = 0.05
Critical region: z<-1.96 or z>+1.96
---------------------------------------------
B)hou greater than27 and hau less than 27 null = 0.10
Ho: u >= 27
Ha: u < 27
alpha = 10%
----
Critical region: z < -1.2816
----------------------------------------------
C)hou less than 60 and hau greater than 60 null = 0.01
Ho: u <= 60
Ha: u > 60
alpha = 1%
Critical region: z > 2.3263
