(SHOW YOUR COMPLETE WORK) A project network is shown below, with three time estimates (Optimistic Time-Most Likely Time-Pessimistic Time (in weeks)) for each activity in the network. 13-16-17.5 12-16-17 B E 14-16-18 H 0-0-0 14-15-19 12.5-15-19 15-17-22 0-0-0 Start End 16-17-21 14-15.5-17 13-14-18 a. Compute the expected time for cach activity in the project network. 19 points b. Identify and list all possible paths in the project network. Compute the expected duration for each path in the project network. [15 points c. Identify the critical path(s) in the project network. What is the expected project completion time? 14 points! d. Compute the variance of each activity on the critical path(s), 15 points c. Determine the project variance and project standard deviation 15 points Use the PERT analysis results in 2c) and 2(c) to answer questions (1), (g)(h), and (i) below: f.
