aint 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 ting in the cans within 0.5 ounce. Assume the population of volumes is normally distributed. Determine the minimum sample size required to construct a 90% confidence interval for the population mean. Assume the population standard deviation is 0.74 ance. The sample mean is 127.75 ounces. With a sample size of 7, a 90% level of confidence, and a population standard deviation of 0.74 ounce, does it seem ossible that the population mean could be exactly 128 ounces? Explain.

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 0.5 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 0.74 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 0.74 ounce, does it seem possible that the population mean could be exactly 128 ounces? Explain. Links are provided to view page 1 and page 2 of the Standard Normal Table. (a) The minimum sample size required to construct a 90% confidence interval is ______ cans. (Round up to the nearest whole number.)
