The American Statistical Association publishes a monthly magazine sent to all of its members. This magazine once included an article that asked, “How many chocolate chips are there in a bag of Chips Ahoy cookies?” (Warner &

Rutledge, 1999). Nabisco, the makers of these cookies, claims there are (at least) 1,000 chocolate chips in each 18-ounce bag of cookies. The authors tested this claim by obtaining 42 bags of cookies, dissolving the cookies in water to separate the chocolate chips from the dough, and counting the number of chocolate chips in each bag. For the sake of simplicity, the number of chips in 18 of their bags is listed below (these 18 bags are representative of the larger sample of 42 bags):
