A soccer ball manufacturer wants to estimate the mean circumference of soccer balls within 0.18 inch. (a) Determine the minimum sample size required to construct a 99% confidence interval for the population mean. Assume the population standard deviation is 0.7 inch. (b) The sample mean is 28.5 inches. With a sample size of 110, a 99% level of confidence, and a population standard deviation of 0.7 inch, does it seem possible that the population mean could be less than 28.6 inches? Explain.

(a) The minimum sample size required to construct a 99% confidence interval is (Round up to the nearest whole number.) soccer balls.
