A random sample of n observations is selected from a normal population to test the null hypothesis that μ = 10. Specify the rejection region for each of the following combinations of Ha, a, and n:

a. Ha: μ ≠ 10; α = .05; n = 14

b. Ha: μ > 10; α = .01; n = 24

c. Ha: μ > 10; α = .10; n = 9

d. Ha: μ < 10; α = .01; n = 12

e. Ha: μ ≠ 10; α = .10; n = 20

f. Ha: μ < 10; α = .05; n = 4
