With a variable life insurance policy, the rate of return on the investment (the death benefit) varies from year to year. A study of these variable return rates was published in a certain journal. A transformed ratio of the return rates (x) for two consecutive years was shown to have a normal distribution, with u = 2.7 and o = 0.2. Use the standard normal table or statistical software to find complete parts a through c. a. P(2.2 2.8) P(x > 2.8) =| (Round to three decimal places as needed.)
