Nielsen Media Research conducted a study of household viewing times between 8:00 PM and 11:00 PM. The sample data in Nielsen.xls are consistent with their findings. Based upon previous studies, assume the population standard deviation is known to be 3.5 hours. Download Nielsen.xls from the "Some Datasets" folder. Now use the sample data in the Excel file along with your knowledge of the population standard deviation to develop a 95% confidence interval estimate for the true mean television viewing time per week during the 8:00 PM to 11:00 PM time period: 95% CI is A/ < population mean (mu) < (Round answer to 2 decimal places.) Now calculate a 99% confidence interval estimate: 99% CI is A/ < population mean (mu) < answer to 2 decimal places.) E A (Round
