You are given the sample mean and the population standard deviation. Use this informationconvenient, use technology to construct the confidence intervals.construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. IfA random sample of 60 home theater systems has a mean price of $130.00. Assume the population standard deviation is $17.40.Construct a 90% confidence interval for the population mean.The 90% confidence interval is ( ).(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 wider than the 90%.O B. 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%.OC. 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%06
