Compute the mean and variance of PW of this project at i-9% if A1 and A2 are mutually independent. The mean of PW is S 64. (Round to the nearest dollar.) The variance of PW is 4,705 dollars squared. (Round to the nearest whole number.) 2. Compute the mean and variance of PW of this project at i-9% if A1 and A2 are partially correlated with P12-035 The mean of PW is S 64. (Round to the nearest dollar.) The variance of PW is 6,340 dollars squared. (Round to the nearest whole number.) (b) In part (a)(1), if random variables (A1 and A2) are normally distributed with the mean and variance as specified in the table, compute the probability that the PW will be negative The probability that the PW will be negative is 17.37%. (Round to two decimal places.)
