Consider a project that has been modeled as shown in the following table. (a) Draw the PERT/CPM network for this project and determine the project's expected completion time (in hours). hr Determine the project's critical path. (Enter your answers as a comma-separated list.) (b) Can activities E and G be performed simultaneously without delaying the minimum project completion time? Yes No (c) Can one person perform A,G, and I without delaying the project? Yes No (d) By how much (in hours) can activity G be delayed without delaying the entire project? hr By how much (in hours) can activity L be delayed without delaying the entire project? hr (e) How much would the project be delayed if activity G was delayed by nine hours and activity L was delayed by six hours? Explain. The project would be delayed hours since G and L on the same path
