Question

Question;Using the table below what is the latest possible time that C may be started without delaying completion of the project? All times are in weeks.Activity Immediate prececessor TimeA 4B 3C A 2D B 7E C,D 4F B 5G E,F 4 0 4 8 10Question 2. 2. The process of smoothing out the utilization of resources in a project is called (Points: 1) CPM. PERT. project crashing. resource leveling.Question 3. 3. Given an activity's optimistic, most likely, and pessimistic time estimates of 4, 6, and 14 days respectively, compute the PERT expected activity time for this activity. (Points: 1) 8 6 7 9Question 4. 4. Given the following small project, the critical path is ________ days.Activity Immediate prececessor TimeA 10B 4C A,B 6 (Points: 1) 10 14 16 20Question 5. 5. Your company is considering submitting a bid on a major project. You determine that the expected completion time is 150 weeks and the standard deviation is 10 weeks. It is assumed that the normal distribution applies. You wish to set the due date for the project such that there is a 95 percent chance that the project will be finished by this time. What due date should be set? (Points: 1) 108.0 160.4 166.5 135.0Question 6. 6. Given the following small project, the critical path is ________ days.

All times are in weeks.Activity Immediate prececessor TimeA -- 4B -- 3C A 2D B 7E C,D 4F B 5G E,F 4 (Points: 1) 0 5 3 6Question 8. 8. Given an activity's optimistic, most likely, and pessimistic time estimates of 4, 14, and 18 days respectively, compute the PERT expected activity time for this activity. (Points: 1) 14 12 11 13Question 9. 9. In a PERT network, the latest (activity) start time is the (Points: 1) earliest time that an activity can be finished without delaying the entire project. latest time that an activity can be started without delaying the entire project. earliest time that an activity can start without violation of precedence requirements. latest time that an activity can be finished without delaying the entire project.Question 10. 10. PERT (Points: 1) assumes that we do not know ahead of time what activities must be completed. assumes that activity time estimates follow the normal probability distribution. is a network technique that uses three time estimates for each activity in a project. is a deterministic network technique that allows for project crashing.Question 11. 11. The expected time in PERT is (Points: 1) a weighted average of the most optimistic time, most pessimistic time, and four times the most likely time. the modal time of a beta distribution. a simple average of the most optimistic, most likely, and most pessimistic times. the square root of the sum of the variances of the activities on the critical path.Question 12. 12. Your company is considering submitting a bid on a major project. You determine that the expected completion time is 100 weeks and the standard deviation is 10 weeks. It is assumed that the normal distribution applies. You wish to set the due date for the project such that there is an 85 percent chance that the project will be finished by this time. What due date should be set? (Points: 1) 108.0 110.4 89.6 85.0Question 13. 13. The expected time in PERT is (Points: 1) greater than the most likely time. equal to the most likely time. less than the most likely time. any of the aboveQuestion 14. 14. The work breakdown structure involves identifying the ________ for each activity. (Points: 1) time cost predecessors All of the aboveQuestion 15. 15. Slack time in a network is the (Points: 1) amount of time that an activity would take assuming very unfavorable conditions. shortest amount of time that could be required to complete the activity. difference between the expected completion time of the project using pessimistic times and the expected completion time of the project using optimistic times. amount of time that an activity can be delayed without delaying the entire project.Question 16. 16. Consider a project that has an expected completion time of 50 weeks and a standard deviation of 9 weeks. What is the probability that the project is finished in 57 weeks or fewer? (Round to two decimals.) (Points: 1) 0.68 0.78 0.22 0.32Question 17. 17. In PERT, we assume that (Points: 1) the times to complete individual activities are known with certainty. all activities are carried out by staff from our own organization. the total cost of a project is independent of the time to complete the project. the total time to complete all activities on the critical path is described by a normal distribution.Question 18. 18. Given an activity's optimistic, most likely, and pessimistic time estimates of 3, 5, and 13 days respectively, compute the expected time for this activity. (Points: 1) 3 4 5 6Question 19. 19. Which of the following is not a concept associated with CPM? (Points: 1) normal time probability normal cost crash costQuestion 20. 20. Using the data in the table below, what is the minimum possible time required for completing the project? All times are in weeks.Activity Immediate prececessor TimeA -- 4B -- 3C A 2D B 7E C,D 4F B 5G E,F 4 (Points: 1) 8 12 18 10
