Test Hypotheses Regarding Two Population Standard Deviations
-A random sample of 21 women had cholesterol levels with a variance of $1107.2$ . A random sample of 18 men had cholesterol levels with a variance of 737.28. Test the hypothesis that the cholesterol levels for women have a larger variance than those for men. Use $\alpha = 0.01$ . Assume the samples were randomly selected from normal populations.
