Xenical is used to treat obesity in people with risk factors such as diabetes, high blood pressure, and highcholesterol or triglycerides. Xenical works in the intestines, where it blocks some of the fat a person eatsfrom being absorbed. A standard prescription of Xenical is given in 110-milligram (mg) capsules. Althoughthe capsule weights can vary somewhat from 110 mg and also from each other, keeping the variation smallis important for various medical reasons. A sample of 26 Xenical capsules had the weight shown in the tablebelow:109.9110.1109.9 109.7110.1109.7110.2110.1110110110.2110109.9110.1109.9110.1109.9109.9109.9110.1110109.9109.9110110.1110.3The mean of the data set is 110; the sample standard deviation is 0.143.
