B) 5
C) 8
D) 15

Question

Quizplus · Accepted Answer

The degrees of freedom for a chi-square test is calculated by multiplying one less than the number of levels for each variable being tested. In this case, we have two variables (F1 and F10) and each variable has 3 and 5 levels, respectively. Therefore, the degrees of freedom for this test would be (3-1) x (5-1) = 8. So, the best choice is C) 8.
