Test Hypotheses Regarding Two Population Standard Deviations
-A medical researcher suspects that the variance of the pulse rate of drinkers is higher than the variance of the pulse rate of non-drinkers. Use the sample statistics below to test the researcher's suspicion. Use $\alpha = 0.05$


Assume the samples were randomly selected from normal populations.
