When testing for the difference between 2 population variances with sample sizes of n1 = 8 andn2 = 10, where n1 has the larger variance, the number of degrees of freedom are
A)8 and 10.
B)7 and 9.
C)18.
D)16.

Question

Quizplus · Accepted Answer

The degrees of freedom for each sample are calculated as the sample size minus one. Therefore, for n1 = 8, the degrees of freedom are 8 - 1 = 7, and for n2 = 10, the degrees of freedom are 10 - 1 = 9.
