Answer #1

a. If proportions of a sample distribution match those of a population specified by the null hypothesis

Explanation:

We know that the null and alternative hypotheses for the Chi-square test for the goodness of fit are given as below:

Null hypothesis: H0: Data follows the given distribution.

Alternative hypothesis: Ha: Data do not follow the given distribution.

So, we check whether proportions of a sample distribution match those of a population specified by the null hypothesis.
