You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% contidence intervals for the 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 $149.00. Assume the population standard deviation is $19.90. ..... Construct a 90% confidence interval for the population mean. The 90% confidence interval is ( 143.47, 154.53) (Round to two decimal places as needed.) Construct a 95% confidence interval for the population mean. The 95% confidence interval is ( ). (Round to two decimal places as needed.)
