Suppose that you have to schedule and coordinate the various activities for a custom app project. The project can be subdivided into the following ten activities. Activity Immediate Activity Time Predecessor (days) A 10 B 8 C A 11 D A 6 E A 17 F C 4 G C, D 6 H B, E 8 H 5 J F, G, I 7 Total = 82C F 11 4 A D G C 10 6 6 7 Start E H I S Finish 17 8 5 B 8{a} Fill in the activity nodes. {b} The critical path is . If you get more than one critical path, please select the upper one. For example, if you have A-C-G-J and B-H-l-J. then you have to select A-C-G-J. {c} The expected optimal completion time is E(t) 2 days. [d] Based on the results for the questions [a}-[b}, answer the following questions: - How many days the actiyity B can be delayed without increasing the expected project completion time? - Is it possible that the actiyity H is delayed without increasing the expected project completion time
