What is evaluated by the chi-square test for goodness of fit?

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

b. If the frequencies found within an individual category match a certain shape

c. Whether the means of two or more categories differ from one another

d. Whether two variables are related to each other or independent

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.
