Textbook Question

Chapter 2, Problem 2.92CRP

Suppose that the owner of the restaurant in Problem 2.91 also wants to study the demand for dessert during the same time period. 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 entrĂ©e was ordered. Data were collected from 630 customers and organized in the following contingency tables:
