D) degrees of freedom increase.

Question

Quizplus · Accepted Answer

The chi-square distribution becomes more symmetrical as the degrees of freedom increase. This means that as the sample size increases, the chi-square distribution becomes more normal in shape. As the degrees of freedom increase, the curve shifts rightwards, becoming more symmetric. So, the best choice is (D) degrees of freedom increase.
