#14 A medical devices company wants know the number of hours its MRI machines are used per day. A previous study found a standard deviation of six hours. How many MRI machines must the company find data for in order to have a margin of error of at most 0.70 hour when calculating a 98% confidence interval? (Due to the rounding of z when working the problems by hand, hand working and Excel may yield slightly different answers.) Multiple Choice 397.61 399 475.69 476

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
A marine biologist would like to estimate the mean weight of all mahi mahi on the Treasure Coast, using a 99% confidence interval. The standard deviation of the weights of all mahi mahi on the Treasure Coast is known to be 8.2 pounds. How large a sample of mahi mahi should the marine biologist select so that the estimate is within 0.88 pounds of the true population mean. Round the solution up to the nearest whole number. n=
