You are given the sample mean and the population standard de f convenient technology to construct the confidence interve Previous question to construct the 90% and 95% confidence intervals for the population mean interpret the results and compare the withs of the confidence intervals A random sample of 60 home theater systems has a mean price of $112.00. Assume the population standard deviation is $17.40. Construct a 90% confidence interval for the population mean The 90% confidence interval (Round to two decimal places as needed) Construct a 95% confidence interval for the population mean The 95% confidence interval is (Round so two decimal places as needed) GHD Interpret the results. Choose the correct answer below CA W s0% confidence, it can be said that the population mean proe lies in the first interval. With 95% confidence, Il can be said that the population mean price lies in the second interval The 85% confidence interval is wider than the 005 OB W 50% confidence, & can be said that the sample mean price lies in the first interval Win 95% confidence, it can be said that the sample mean price les in the second interval. The 85% confidence intamal is wider than the 90% OC. W 90% sonfiderice, can be said that the population mean price With 95% confidence, it can be said that the population mean price les in the second interval The 95% confidence interval is name th the 90%
