Question
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
