Which of the following statements is true in the context of a chi-square goodness-of-fit test?

b. The degrees of freedom for determining the critical value will be the number of categories minus 1.

Explanation:

The critical value will come from the chi square table even though the sample size exceeds 30.

A very large test statistic will result in the null being rejected.

The null hypothesis will be rejected for a large value of the test statistic.

The degrees of freedom for Chi square test for goodness of fit is number of categories minus 1.
