Question:

Test each of the following hypotheses by using the given information. Assume the populations are normally distributed.

a. H0: σ2 = 20

Ha: σ2 > 20

α = .05, n = 15, s2 = 32

b. H0: σ2 = 8.5

Ha: σ2 ≠ 8.5

α = .10, n = 22, s2 = 17

c. H0: σ2 = 45

Ha: σ2 > 45

α = .01, n = 8, s2 = 4.12

d. H0: σ2 = 20

Ha: σ2 ≠ 20

α = .05, n = 11, s2 = 1.2
