Suppose that the owner of the restaurant in Problem 2.81 also wanted to study the demand for dessert during the same time period. She decided that in addition to studying whether a dessert was ordered, she would also study the gender of the individual and whether a beef entrée was ordered. Data were collected from 600 customers and organized in the following contingency tables:

a. For each of the two contingency tables, construct contingency tables of row percentages, column percentages, and total percentages.
b. Which type of percentage (row, column, or total) do you think is most informative for each gender? For beef entrée? Explain.
c. What conclusions concerning the pattern of dessert ordering can the restaurant owner reach?
