Question 582457: 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 ≤ 24 and Ha: µ >24, α = 0.01
b. H0: µ =61 and Ha: µ ≠ 61, α = 0.05
c. H0: µ ≥27 and Ha: µ <27, α = 0.10

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 ≤ 24 and Ha: µ >24, α = 0.01
Right-tail test: CV = invNorm(0.99) = 2.3263
-----------------------------------------------------
b. H0: µ =61 and Ha: µ ≠ 61, α = 0.05
Two-tail test: CV = +-1.96
-----------------------------------------------------
c. H0: µ ≥27 and Ha: µ <27, α = 0.10
Left-tail test: invNorm(0.10) = -1.2816
======================================================
