Nielsen Media Research wants to estimate the mean amount of time (in minutes) that fulltime college students spend watching television each weekday. Find the sample size necessary to estimate that mean with 15-min margin of error. Assume that a 96% confidence level is desired. Also assume that a pilot study showed that the standard deviation is estimated to be 112.2 minutes. show work

Nielsen Media Research wants to estimate the mean amount of time (in hours) that full-time college students spend watching television each weekday. Find the sample size necessary to estimate that mean with a 0.25 h (or 15 min) margin of error. Assume that a 96% degree of confidence is desired. Also assume that a pilot study showed that the standard deviation is estimated to be 1.87 hours.

A survey is being planned to determine the mean amount of time corporation executives watch television. A pilot survey indicated that the mean time per week is 12 hours, with a standard deviation of 3 hours. It is desired to estimate the mean viewing time within one-quarter hour. The 95 percent level of confidence is to be used. How many executives should be surveyed?
