Which of the following is NOT true of the goodness-of-fit test? Choose the correct answer below. A. Expected frequencies need not be whole numbers. B. If expected frequencies are not all equal, then we can determine them by Eequals=np for each individual category, where n is the total number of observations and p is the probability for the category. C. If expected frequencies are equal, then we can determine them by Upper E equals StartFraction n Over k EndFractionE= n k, where n is the total number of observations and k is the number of categories. D. Goodness-of-fit hypothesis tests may be left-tailed, right-tailed, or two-tailed.
