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 F/2 and FL can be denoted F1-/2 .

Find the critical values FL and FR for a two-tailed hypothesis test based on the following

values: n1 = 25, n2 = 16, = 0.10
