Explain why you cannot perform the chi-square independence test on these data. Conditional Relative Frequencies In Exercises 32-39, use the contingency table from Exercises 29-31, and the following information. Relative frequencies can also be calculated based on the row totals (by dividing each row entry by the row's total) or the column totals (by dividing each column entry by the column's total). These frequencies are conditional relative frequencies and can be used to determine if an association exists between two categories in a contingency table.
