7. Consider the following hypotheses:

H0: σ 2 = 200 HA: σ2 ≠ 200 Approximate the p-value based on the following sample information, where the sample is drawn from a normally distributed population.

a. s2 = 300; n = 25

b. s2 = 100; n = 25

c. Which of the above sample information enables us to reject the null hypothesis at α = 0.05?
