Internet Viewing A researcher wishes to estimate the average number of minutes per day a person spends on the Internet. How large a sample must she select if she wishes to be 95% confident that the population mean is within 7 minutes of the sample mean? Assume the population standard deviation is 36 minutes. Round your final answer up to the next whole number. The researcher needs a sample of at least people.
