What is the expected completion time for the project? 3. Find the critical path for the network. 4. State the non-critical activities. 5. Explain what it means if an activity has a slack of zero. 6. Explain what it means if an activity has a slack of non-zero. QUESTION 2 On Blackboard, go to Assignments and print the file "Project Management". Using the table in problem 3.17, answer the following questions: a) Determine the expected time for each activity. b) Determine the variance and standard deviation for each activity. c) Using the critical path A-C-F--H--)K, determine the expected completion time for the project. d) Determine the variance and standard deviation for the project. e) What is the probability of completing the project in less than 40 weeks? f) What is the probability of completion of the project before week 36? softw house listed shorten the project is worth $250 to you.
