Quizplus · Accepted Answer

The critical value for F with α = .05, a numerator degrees of freedom of 8 and a denominator degrees of freedom of 20 is 2.45. Since the question specifies that the sample with the smaller variance has a sample size of 21, we know that this sample corresponds to the denominator degrees of freedom. Therefore, the critical value is 2.45.
