Part 2. Perform PERT calculations using the data set in problem 9. Did the project duration change with the PERT analysis? If so, why?
(Use the schedule created in question 5 but adjust the durations using PERT calculation from the three-point estimates below and recalculate slack. Task A, Optimistic = 1, Normal = 2, Pessimistic = 5 Task B, Optimistic = 2, Normal = 4, Pessimistic = 8 Tack C, Optimistic = 3, Normal = 7, Pessimistic = 12 Task D, Optimistic = 3, Normal = 5, Pessimistic = 10 Task E, Optimistic = 1, Normal = 3, Pessimistic = 6 Task F, Optimistic = 3, Normal = 8, Pessimistic = 15 Task G, Optimistic = 7, Normal = 10, Pessimistic = 22 Task H, Optimistic = 3, Normal = 4, Pessimistic = 6 Task I, Optimistic = 5, Normal = 7, Pessimistic = 12 Task J, Optimistic = 10, Normal = 12, Pessimistic = 15)
