A company packaging potato chips maintains quality control by randomly selecting 20 cases from each day's production and weighing the bags.Then they open one bag from each case and inspect the contents Using these two methods, they determine the number of bags that pass inspection. C. proportion of people who do not eat potato chips D. proportion of bags passing inspection c) The sampling frame A. people who eat potato chips B. all bags produced each day C. 20 bags, one from each of 20 randomly selected cases D. bags of potato chips d) The sample A. proportion of people who eat potato chips B. 20 bags, one from each of 20 randomly selected cases C. all bags produced each day D. bags of potato chips e) The sampling method including whether or not randomization was employed A. questionnaire (non-random) B. not specified, non-random C. multistage sampling Presumably they take a simple random sample of 20 cases, followed by a simple random sample of one bag from each case. D. not specified, but at least "random"
