A research group wishes to estimate the main number of hours that high school students been watching TV on a weekday. Margin of error of error of E = 0.15 Our is desired. Past study suggests that population standard deviation of ? = 2.6 ours is reasonable. Estimate the minimum sample size required to estimate the population mean with 95% confidence.
