Hi, I need help answering the last question. Rob Smith is managing a small project at Boston University. He is under pressure to shorten the overall duration of the project by 4 weeks and he wants to do so at the lowest cost possible. In order to meet this objective a number of activities must be crashed. Activity Normal Time (weeks) Crashed Time (weeks) Normal Cost Crashed Cost Predecessor(s) A 5 3 $800 $1,200 - B 6 5 $300 $450 - C 6 5 $550 $775 - D 3 2 $750 $950 A E 6 3 $1,350 $2,250 C F 5 3 $675 $875 B What is the total cost of crashing the project 4 weeks (just the additional cost, not total project cost)? (Display your answer to two decimal places.)

Image of Diagram included Using the diagram, find: The critical path. How long it will take to complete the project? How does simulation determine the probabilities of various project completion times? What is "slack" and why is it important? Why is activity-on-arrow (AOA) or activity-on-node (AON) of significant value to the project manager? How is the uncertainty in project scheduling dealt with? Should the critical path activities be managed differently from noncritical path activities? Explain.
