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
