Assume that the population of volumes is normally distributed.?(a) The company wants to estimate the mean volume of water the machine is putting in the bottles within 1 milliliter. Determine the minimum sample size required to construct a 9090?% confidence interval for the population mean. Assume the population standard deviation is 55milliliters.?(b) Repeat part? (a) using an error tolerance of 22 milliliters. Which error tolerance requires a larger sample? size? Explain.
