Test for the Differnce of Two Variances

The null hypothesis is that the two population variances are equal, consequently, their ratio will equal 1. In setting up a one tailed alternative hypothesis that one variance is larger than the other, we will put the larger variance in the numerator.

H0: σL2S2 = 1.0

H1: σL2S2 > 1.0
