A coin-operated soda machine was designed to discharge, on the average, 7 ounces of beverage per cup. To test the machine, a random sample of 15 cupfuls of soda was drawn from the machine and measured. The results were as follows: 6.95 7.00 6.99 6.92 6.88 6.98 7.02 7.00 6.99 7.10 7.01 6.96 7.04 7.00 7.05 Assuming that the amount of beverage dispensed is normally distributed, compute a 99% confidence interval estimate for µ=mean amount of soda dispensed (in ounces).
