A soccer ball manufacturer wants to estimate the mean circumference of mini-soccer balls within 0.15 inch. Assume the population of circumferences 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 0.25 inch. (b) Repeat part (a) using a population standard deviation of 0.15 inch. (c) Which standard deviation requires a larger sample size? Explain (a) The minimum sample size with a population standard deviation of 0.25 inch is (Round up to the nearest integer.) balls. (b) The minimum sample size with a population standard deviation of 0.15 inch is (Round up to the nearest integer.) balls. V sample size to (c)A population standard deviation of V inch requires a larger sample size because greater variability in the population requires a ensure the desired accuracy.
