This statement is true. When dealing with nominal data with exactly two categories, we can use either the z-test of a population proportion p or the chi-squared goodness-of-fit test to describe the population. The z-test determines whether the proportion of one of the categories is significantly different from a predetermined value, while the chi-squared test determines whether the observed frequencies of the two categories are significantly different from the expected frequencies.
