Critical Path: b. What is the expected time to complete the project? If necessary, round your answer to two decimal places. E(T) = days c. What is the probability that the project can be completed in 25 or fewer days? Variance = . If necessary, round your answers to two decimal places. Using the normal distribution, z = If necessary, round your answers to two decimal places. If negative answer is required, enter the minus sign before the number. Probability of 25 days or less is If necessary, round your answers to four decimal places. Note: Use Appendix B to identify the probability. Assume that the activity time estimates (in days) for the swimming pool construction project in Problem 11 are as follows: F H Start 1 Finish B D E Optimistie Most Probable Activity D E F G H 1 -NAN +0000 Pessimistie 6 6 7 10 6 3 10 10 5 6 a.
