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 40 home theater systems has a mean price of $150.00. Assume the population standard deviation is $16.20. Construct a 90% confidence interval for the population mean. The 90% confidence interval is ( , ). (Round to two decimal places as needed.)
