The most likely outcomes for a particular project are estimated as follows: however, you recognize that some of these estimates are subject to error. Suppose that each variable may turn out to be either 10% higher or 10% lower than the initial estimate. The project will last for 10 years and requires an initial investment of $1.8 million, which will be depreciated straight-line over the project life to a final value of zero. The firm's tax rate is 40% and the required rate of return is 10%. What is project NPV in the best-case that is, assuming all variables take on the best possible value? What is project NPV in the worst- case scenario
