Finding F critical for Variances
Use the F-distribution to find the degrees of freedon for the numerator (d.f.N.), the degrees of freedom for the Denominator (d.f.D.) and the critical F-value
Use the closest value when looking up the d.f.N. and d.f.D. in the tables.

When performing a hypothesis test for the ratio of two
population variances, the upper critical F value is denoted FR. The
lower critical F value, FL, can be found as follows: interchange
the degrees of freedom, and then take the reciprocal of the
resulting F value found in table A-5. FR can be denoted Fα/2 and FL
can be denoted F1-α/2 . Find the critical values FL and FR for a
two-tailed hypothesis test based on the following values: n1...
