Question 517463: 12. 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) H0:µ=79 and Ha:µ≠79, a=.01
(B) H0:µ≥53 and Ha:µ<53, a=.05
(C) H0:µ≤54 and Ha:µ>53, a=.10

You can put this solution on YOUR website! 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) H0:µ=79 and Ha:µ≠79, a=.01
----
2-tail test ; CV = z = +/-2.5758
------------------------------------
(B) H0:µ≥53 and Ha:µ<53, a=.05
right tail test: CV = z = 1.6449
------------------------------------
(C) H0:µ≤54 and Ha:µ>53, a=.10
right tail test: CV = z = 1.645
====================================
