A coin-operated soda machine was designed to discharge, on the average, 7 ounces ofbeverage per cup. To test the machine, a random sample of 15 cupfuls of soda was drawnfrom the machine and measured. The results were as follows:6.957.006.996.926.886.987.027.006.997.107.016.967.047.007.05Assuming that the amount of beverage dispensed is normally distributed, compute a 99%confidence interval estimate for µ=mean amount of soda dispensed (in ounces).

A pharmaceutical company makes tranquilizers. It is assumed that the distribution for the length of time they last is approximately normal. Researchers in a hospital used the drug on a random sample of 9 patients. The effective period of the tranquilizer for each patient (in hours) was as follows: 2.6; 2.8; 3.0; 2.3; 2.3; 2.2; 2.8; 2.1; and 2.4.NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed.
