What is the critical F value for a sample of 5 observations

What is the critical F value for a sample of 5 observations in the numerator and 8 in the denominator? Use a two-tailed test and the 0.02 significance level.

Solution

degrees of freedom of numerator = 5-1 = 4

degrees of freedom of denominator = 8 - 1 = 7

critical value = F(4,7,0.02) = 6.0347
