When testing for the difference between two population variances with sample sizes of n₁ = 10 and n₂ = 12,what is (are)the number (s)of degrees of freedom?

Question

Quizplus · Accepted Answer

When testing for the difference between two population variances, the number of degrees of freedom is calculated as (n1 - 1) and (n2 - 1) for the two sample sizes n1 and n2. Therefore, the degrees of freedom for this scenario would be (10 - 1) and (12 - 1), which simplifies to 9 and 11. Thus, the correct choice is B, with 9 and 11 as the number of degrees of freedom.
