A soccer ball manufacturer wants to estimate the mean circumference of soccer balls within 0.190.19 inch. (a) Determine the minimum sample size required to construct a 9999% confidence interval for the population mean. Assume the population standard deviation is 0.60.6 inch. (b) The sample mean is 2828 inches. With a sample size of 7676, a 9999% level of confidence, and a population standard deviation of 0.60.6 inch, does it seem possible that the population mean could be less than 28.128.1 inches? Explain. Click here to view page 1 of the Standard Normal Table. LOADING... Click here to view page 2 of the Standard Normal Table. LOADING...
