A magazine includes a report on the energy costs per year for 32-inch liquid crystal display (LCD) televisions. The article states that 14 randomly selected 32-inch LCD televisions have a sample standard deviation of $3.46. Assume the sample is taken from a normally distributed population. Construct 95% confidence intervals for (a) the population variance 2 and (b) the population standard deviation . Interpret the results. (a) The confidence interval for the population variance is (). (Round to two decimal places as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. With 5% confidence, you can say that the population variance is greater than O B. With 95% confidence, you can say that the population variance is between and O C. With 95% confidence, you can say that the population variance is less than O D. With 5% confidence, you can say that the population variance is between and. (b) The confidence interval for the population standard deviation is (]]). (Round to two decimal places as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. With 5% confidence, you can say that the population standard deviation is between and dollars per year. O B. With 95% confidence, you can say that the population standard deviation is greater than dollars per year. O C. With 95% confidence, you can say that the population standard deviation is between |and dollars per year. O D. With 5% confidence, you can say that the population standard deviation is less than dollars per year
