The owner of a restaurant that serves Continental-style entrees has the business objective of learning more about the patterns of patron demand during the Friday-to-Sunday weekend time period. She decided to study the demand for dessert during this time period. In addition to studying whether a dessert was ordered, she will study the gender of the individual and whether a beef entree was ordered. Data were collected from 600 customers and organized in the following contingency tables:

a. At the 0.05 level of significance, is there evidence of a difference between males and females in the proportion who order dessert?
b. At the 0.05 level of significance, is there evidence of a difference in the proportion who order dessert based on whether a beef entree has been ordered?
