The owner of a restaurant serving Continental-style entrees was interested in studying ordering patterns of patrons for the Friday-to-Sunday weekend time period. Records were maintained that indicated the demand for dessert during the same time period. The owner decided to study two other variables, along with whether a dessert was ordered: the gender of the individual and whether a beef entrée was ordered. The results are as follows:
GENDER
DESSERT ORDERED Male Female Total
Yes 96 40 136
No 224 240 464
Total 320 280 600
BEEF ENTRÉE
DESSERT ORDERED Yes No Total
Yes 71 65 136
No 116 348 464
Total 187 413 600
