Evolution theory predicts a physiological cost of increased reproduction that translates into a shorter life span. A study examined the cost of sexual activity in male fruit flies by comparing males allowed to be sexually active with those that were not. The data shows the longevity in days for a sample of sexually inactive males. Assume the standard deviation for longevity of male sexually active fruit flies is 11.95 days. Are the standard deviations for the sexually active and inactive male fruit fly different? Use α = 0.05.
