E Test: Exam3 Question 7 of 11 This test: 11 point(s) possible Submit test This question: 1 point(s) possible 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 01. Assume the sample is taken from a normally distributed population. Construct 90% confidence intervals for (a) the population variance of and (b) the population standard deviation o 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 90% confidence, you can say that the population variance is less O B. With 10% confidence, you can say that the population variance is than between and O C. With 90% confidence, you can say that the population variance is D. With 10% confidence, you can say that the population variance is greater between than 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 90% confidence, you can say that the population standard deviation O B. With 90% confidence, you can say that the population standard deviation is between and dollars per year Is greater than dollars per year O C. With 10% confidence, you can say that the population standard deviation O D. With 10% confidence, you can say that the population standard deviation is between and dollars per year is less than dollars per year
