A random sample of n observations is selected from a normal population to test the null hypothesis

Question:

A random sample of n observations is selected from a normal population to test the null hypothesis that σ2 = 25. Specify the rejection region for each of the following combinations of Ha, α, and n:

a. Ha: σ2 ≠ 25; α = .05; n = 16

b. Ha: σ2 > 25; α = .01; n = 23

c. Ha: σ2 > 25; α = .10; n = 15

d. Ha: σ2 < 25; α = .01; n = 13

e. Ha: σ2 ≠ 25; α = .10; n = 7

f. Ha: σ2 < 25; α = .05; n = 25
