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 $3.24. Assume the sample is taken from a normally distributed population. Construct 80% confidence intervals for (a) the population variance o and (b) the population standard deviation a. Interpret the results. (a) The confidence interval for the population variance is (Round to two decimal places as needed.)
