I and II are true statements. The chi-square Goodness of Fit Test can be used to compare sample proportions to theoretical values, as well as to compare observed frequencies to expected frequencies.

III is a false statement. A chi-square GOF test does not require the calculation of mean and standard deviation.

IV is a true statement. There are no assumptions about the shape of the distribution in a chi-square GOF test, only that the expected values are not too small.
