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 = 10, n2 = 16, α = 0.05
Homework Answers
At 
= 0.05, the critical values are
FL = F(0.975, 9, 15) = 0.2653
FR = F(0.025, 9, 15) = 3.1227

In a two-tailed F-test about equality of two population variances, given n1=21, S21 = 8.2, n2=26,S22= 4.0, and alpha = 0.05. The numerator and denominator degrees of freedom for the F distribution, respectively, are: The computed value of the test statistic, F, is: The critical value of F, from F chart or using MS Excel, is: The p-value, from F chart or using MS Excel, is: The conclusion is to reject H0. True or False?
