F Statistic Ratio of Variances

Problem

The F statistic for comparing two variances is the larger sample variance divided by the smaller under the two-sided test convention used here: s1^2 / s2^2.

Given the two sample variances, return the ratio.

Hint

Variance ratios follow an F distribution under normality.
