The range for the rate of return for camera Ris%. (Round to the nearest whole number.) The range for the rate of return for camera Sis%. (Round to the nearest whole number.) b. The value of the expected return for camera R is %. (Round to two decimal places.) The value of the expected return for camera Sis %. (Round to two decimal places.) c. Which camera purchase is riskier? Why? (Select from the drop-down menus.) The purchase of is riskier because it has a range for the rate of return.
