9pm 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 $3.43, Assume the sample is taken from a normally distributed population. Construct 95% confidence intervals 17/22 59pm for (a) the population variance o and (b) the population standard deviation a Interpret the results 01/22 59pm (a) The confidence interval for the population variance is (| |) (Round to two decimal places as needed.) 101/22 Interpret the results. Select the correct choice below and fill in the answer boxes) to complete your choice :59pm (Round to two decimal places as needed ) 5/01/22 A. With 5% confidence, you can say that the population variance is B. With 95% confidence, you can say that the population variance is less 1:59pm between than and 5/01/22 1:59pm C.
