One researcher wishes to estimate the mean number of hours that high school students spend watching TV on a weekday. A margin of error of 0.25 hour is desired. Past studies suggest that a population standard deviation of 1.9 hours is reasonable. Estimate the minimum sample size required to estimate the population mean with the stated accuracy. The required sample...
