When performing 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 = 10, n2 = 16, ? = 0.05
a. 0.3202, 3.1227
b. 0.2653, 3.1227
d. 3.1227, 3.7743
