You are given the sample mean and the population standard deviation. Use this information to construct the 90% to 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If convenient use technology to construct the confidence intervals. A random sample of 60 home theater systems has a mean price of $114.00. Assume the population standard deviation is $19.20. Construct a 90% confidence interval for the population mean. (round to two decimal places.) Construct a 95% confidence interval for population mean. (round to two decimals places)
