Question 24 (15 points) onsider the following PERT/CPM network with estimated times in weeks B 3 Start 2 H 2 Finish 4 1.5 F 1.2 The three-time estimate approach was used to calculate the expected times and the following table gives the variance for each activity Activity Variance Activity Variance E 0.3 B 0.5 0.6 C G 0.6 D 0.8 Give the expected project completion time, the critical path of the project, and what is the probability that the project will be completed within 19 weeks? The answer should be given in the following format: Expected project completion time; The critical path of the project, The probability that the project will be completed within 19 weeks 17; Start-A-B-E-F-H-Finish: 0.8438 H 1.0 16; Start-A-B-D-G-H-Finish: 0.0764 17: Start-A-B-D-G-H-Finish: 0.8289 V.U 0.8 1.0 Give the expected project completion time, the critical path of the project, and what is the probability that the project will be completed within 19 weeks?
