statistics

You are given the sample mean and the population standard deviation. Use this Information to construct the 90% and 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 35 home theater systems has a mean price of $121.00. Assume the population standard deviation is $19.40. Construct a 90% confidence interval for the population mean. The 90% confidence interval is ()- (Round to two decimal places as needed.) " 4
