10. (2 points) For the following annual cash-flow estimates, find the E(PW), V(PW), and SD(PW) of the project. Assume that the annual net cash-flow amounts are normally distributed with the expected values and standard deviations as given and statistically independent and that the MARR = 10% per year.
