We have a normal distribution, and want to make a hy- pothesis test on its variance. Precisely, H0 : σ2 = 25 vs H0 : σ2 6 = 25. The size of the sample we are using is 61. (a) (6 points) Find the rejection region at the significance level 0.02. (b) (6 points) We have a sample for which s = 5.4. What is your conclusion at the significance level 0.02 (c) (3 points) We have a sample for which s = 3.9. Approximate the P-value.
