The company's president must determine whether to make the expansion a medium- or large-scale project. Demand for the new product is uncertain, which for planning purposes may be low demand, medium demand, or high demand. The probability estimates for demand are 0.30,0.50, and 0.20 , respectively. Letting x and y indicate the annual profit in thousands of dollars, the firm's planners developed the following profit forecasts for the medium-and large-scaie expansion projects. (a) Compute the expected value (in thousands of dollars) for the profit associated with the two expansion alternatives. Medium-Scale x thousand dollars Large-Scale x thousand dollars Which decision is preferred for the objective of maximizing the expected profit? The x Expansion Profit forecast is preferred for the objective of maximizing the expected profit. (b) Compute the variance for the profit associated with the two expansion alternatives. Medium-Scale x Large-Scale x Which decision is preferred for the objective of minimizing risk or uncertainty? The x Expansion Profit forecast is preferred for the objective of minimizing risk or uncertainty
