Xenical is used to treat obesity in people with risk factors such as diabetes, high blood pressure, and high cholesterol or triglycerides. 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 110-milligram (mg) capsules. Although the capsule weights can vary somewhat from 110 mg and also from each other, keeping the variation small is important for various medical reasons. A sample of 26 Xenical capsules had the weight shown in the table below: 109.9 110.1 109.9| 109.7 110.1 109.7 110.2 110.1 110 110 110.2 110 109.9 110.1 109.9 110.1 109.9 109.9 109.9 110.1 110 109.9 109.9 110 110.1 110.3 The mean of the data set is 110; the sample standard deviation is 0.143.

Transcribed Image Text:Xenical is used to treat obesity in people with risk factors such as diabetes, high blood pressure, and high
cholesterol or triglycerides. 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 110-milligram (mg) capsules. Although
the capsule weights can vary somewhat from 110 mg and also from each other, keeping the variation small
is important for various medical reasons. A sample of 26 Xenical capsules had the weight shown in the table
below:

The mean of the data set is 110; the sample standard deviation is 0.143. Assuming that the population is
normal, construct a 95% confidence interval for the variance of all Xenical capsule weights.
