We want to know whether the variance of the aerobic capacity of smokers is greater than the variance in non smokers. We test the aerobic capacity of n1=21 smokers and n2=18 non smokers and obtain s12=13 and s22=3. Test the nulll hypothesis that the variance are the-same against the alternative hypothesis that they are different using alpha=0.01.
