A test designed to measure level of anxiety was administered

A test designed to measure level of anxiety was administered to a sample of male and a sample of female patients just prior to undergoing the same surgical procedure. The sample sizes and the variances computed from the scores were as follows: Males: n=16, s2 = 150 Females n=21 s2 = 275 Do these data provide sufficient evidence to indicate that in the represented populations the scores made by females are more variable than those made by males? Perform a test of hypothesis at the 5% level (=.05) using the F-statistic.
