Given the information below: a. This project will be completed in days. b. Is task A critical?(type yes or no): c. Task B has a total float of days. A project team estimates that a work package is most likely to have a duration of 9 days. However, under the worst possible conditions (pessimistic) it will take 15 days, and if conditions are ideal (optimistic), it will take only 3 days. Using the PERT three-point estimation method, what is the expected time for this work package? 18 days 14 days 9 days 26.67 days None of the above Activity E has these Estimates for duration: Optimistic =91 days, Most likely =96 days, pessimistic = 103 days. What is the estimated standard deviation for activity E? 1 2 4 16 None of the above
