Now conduct a scenario analysis. Assume that there is a 20% probability that best-case conditions, with each of the variables discussed in Part b being 20% better than its base-case value, will occur. There is a 20% probability of worst-case conditions, with the variables 20% worse than base, and a 60% probability of base-case conditions. Round your answers for the NPV and standard deviation to the nearest dollar and for the coefficient of variation to two decimal places. Use a minus sign to enter a negative value, if any.
