Xenical works in the intestines, where it blocks some of the fat a person eats from being absorbed. A standard prescription of Xenical is given in 120-milligram (mg) capsules. Although the capsule weights can vary somewhat from 120 mg and also from each other, keeping the variation small is important for various medical reasons. A sample of 20 Xenical capsules had the weight shown in the table below: 120.2 120 120.2 119.6 119.8 120.2 120 119.9 119.9 120.3 120.3 119.9 120.2 120.1 120 120.1 119.9 119.9 120.1 120.2 The mean of the data set is 120; the sample standard deviation is 0.18. Assuming that the population is normal, construct a 95% confidence interval for the variance of all Xenical capsule weights. i. Procedure: Select an answer ii. Assumptions: (select everything that applies) The number of positive and negative responses are both greater than 10 Sample size is greater than 30 Normal population Population standard deviation is known Population standard deviation is unknown Simple random sample iii.
