A paint manufacturer uses a machine to ll cans with paint. The manufacturer wants to estimate the mean volume of paint the machine is putting in the cans within 0.6 ounce. Assume the population of volumes is normally distributed and the population standard deviation is 0.80 ounce. The sample mean is 127.75 ounces with a sample size of 7.
