A restaurant wants to know if more people order its “mega meat pizza” or “mammoth vegetable pizza” depending on whether it is a weekend night or a weekday night. The restaurant keeps track of customers’ preference for these two types of pizza (mega meat or mammoth vegetable) and the night of the week it’s ordered (weekend night or weekday night) over 2 weeks. It finds that a total of 150 people ordered one of these pizzas, with 60 ordering mega meat on a weekend night, 20 ordering mega meat on a weekday night, 25 ordering mammoth vegetable on a weekend night, and 45 ordering mammoth vegetable on a weekend night. Conduct the appropriate statistical test to see if there is a difference between the frequencies of customers ordering the two types of pizza. Assume that the expected frequencies are equal, and use an alpha of .05
