A paint manufacturer uses a machine to fill gallon cans with paint (1 gal = 128 ounces). 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.
(a) Determine the minimum sample size required to construct a 90% confidence interval for the population mean. Assume the population standard deviation is 0.83 ounce.
(b) The sample mean is 127.75 ounces. With a sample size of 7, a 90% level of confidence, and a population standard deviation of 0.83 ounce, does it seem possible that
the population mean could be exactly 128 ounces? Explain.
