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 conven technology to construct the confidence intervals A random sample of 50 home theater systems has a mean price of $129.00. Assume the population standard deviation is $18.20. Construct a 90% confidence interval for the population mean The 90% confidence interval is ( D (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) Interpret the results Choose the correct answer below O A. With 90% confidence, it can be said that the population mean price lies in the first interval With 95% confidence, it can be said that the population mean price lies in the second interval The 95% confidence interval is narrower than the 90% OB. With 90% confidence, it can be said that the population mean price lies in the first interval With 95% confidence, it can be said that the population mean price lies in the second interval The 95% confidence interval is wider than the 90% O C. With 90% confidence, it can be said that the sample mean price lies in the first interval. With 95% confidence, it can be said that the sample mean price lies in the second interval The 95% confidence interval is wider than the 90%

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 convenier technology to construct the confidence intervals. A random sample of 50 home theater systems has a mean price of $129.00. Assume the population standard deviation is $18.20. Construct a 90% confidence interval for the population mean. The 90% confidence interval is ( l D. (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.) Interpret the results. Choose the correct answer below. O A. With 90% confidence, it can be said that the population mean price lies in the first interval. With 95% confidence, it can be said that the population mean price lies in the second interval. The 95% confidence interval is narrower than the 90%. B. With 90% confidence, it can be said that the population mean price lies in the first interval. With 95% confidence, it can be said that the population mean price lies in the second interval.
