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 1,000 chocolate chips in each 18-ounce bag of cookies. The authors tested this claim by obtaining forty-two18-ounce bag 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. The number of chips in 18 of their 42 bags is provided. The data collected was used to test if the number of chocolate chips in each 18-ounce bag of Chips Ahoy does not support Nabisco’s claim. What is the proposed analysis and why you chose the analysis? Scales of measurement (i.e., nominal, ordinal, interval or ratio) for variable(s) that will be used in the analysis: What is the null and alternative hypotheses (based on context of study) in symbols?
