She decides that in addition to studying whether a dessert was ordered, she will also study the gender of the individual and whether a beef entrée was ordered. Data were collected from 630 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.
