Question 187070: 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 = 25 and Ha: µ ≠ 25, α = 0.10
b. H0: µ ≤ 32 and Ha: µ >32, α = 0.01
c. H0: µ ≥13 and Ha: µ <13, α = 0.05

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. Ho: µ = 25 and Ha: µ ≠ 25, α = 0.10
Critical Values: z = +/-1.645
Critical Region: z < -1.645 or z > +1.645
--------------------------------------------------
b. Ho: µ ≤ 32 and Ha: µ >32, α = 0.01
Critical Value: z = 2.326
Critical Region: z >= 2.326
---------------------------------------------------
c. H0: µ ≥13 and Ha: µ < 13, α = 0.05
Critical Value: z = -1.645
Critical Region: z < -1.645
===================================
