What is the factorial notation for the following design? A pizza parlor owner is interested in what type of pizza is most preferred by his customers. He manipulates the type of crust for the pizzas by using thin, thick, and hand-tossed crusts. In addition, he manipulates the topping for the pizzas by offering cheese, pepperoni, sausage, veggie, and everything. He then has his customers sample the various pizzas and rate them. After you have determined the factorial notation, indicate how many conditions are in this study.
