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 100-milligram (mg) capsules. Although the capsule weights can vary somewhat from 100 mg and also from each other, keeping the variation small is important for various medical reasons. A sample of 25 Xenical capsules had the weight shown in the table below: 100.2 99.9 100.1 100.2 99.9 100 100.1 100 99.9 100.1 99.9 99.9 100.2 100.2 100.2 100.1 99.9 100 100.2 100.2 99.9 99.9 100.2 99.9 99.9 The mean of the data set is 100.04; the sample standard deviation is 0.132. 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.

In 2004, 69% of all Americans owned homes. In 2019, that number was down to 64.8%. A city manager believes that 70% of the population in their town own the house they reside in and a researcher was hired to survey the population. In a simple random sample of 210 occupied housing units, there were 154 that are owner-occupied. Use a 10% significance level to test the claim that the percentage of the population that own a house is greater than 70%.
