Apaint manufacturer uses a machine to fill gallon cans with paint (1 galequals128 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 0.80 ounce.(b) the sample mean is 127 ounces. with a sample size of 8, a 90% level of confidence, and a population standard deviation of 0.80 ounce, does it seem possible that the population mean could be exactly 128 ounces? explain.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
