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.
H_{0}: σ_{L}^{2}/σ_{S}^{2} = 1.0

H_{1}: σ_{L}^{2}/σ_{S}^{2} > 1.0
