Question

A machine is used to fill container with a liquid product. Fill volume can be assumed to be normally distributed. A random sample of 10 containers is selected, and the net contents (oz.) are as follows: 12.03, 12.01, 12.04, 12.02, 12.05, 11.98, 11.96, 12.02, 12.05, and 11.99. Suppose that the manufacturer wants to be sure that the mean net contents exceed 12 oz. What conclusions can be drawn from the data using a 95% two-sided confidence interval on the mean fill volume?
