Question 11.Refer to Question 10.Callaway Golf Company's new forged titanium ERC driver has been described as "illegal" because it promises driving distances that exceed the USGA'sstandard. Golf digest compared actual driving distances with the ERC driver and a USGA-approved driver with a population mean distance of 280yards. Based on nine test drives, the mean driving distance by the ERC driver was 286.9 yards and the standard deviation is 10 yards.i. Find the t value for the calculation of the 99% confidence interval for the population mean driving distance for the new ERC driver.ii. Find the margin of error for a 99% confidence interval for the population mean driving distance for the new ERC driver?iii. Find a 99% confidence interval for the population mean driving distance for the new ERC driver.iv. Find a 72% confidence interval for the population mean driving distance for the new ERC driver. Hint: Use Excel function=t.inv.2t to get the tvalue.
