Question;1.;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;Time;A;4;B;3;C;A;2;D;B;7;E;C,D;4;F;B;5;G;E,F;4;0;4;8;10;Question 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;9;Question 4. 4.Given the;following small project, the critical path is ________ days.;Activity;Immediate prececessor;Time;A;10;B;4;C;A,B;6;(Points: 1);10;14;16;20;Question 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;135.0;Question 6. 6.Given the;following small project, the critical path is ________ days.;(Points: 1);Activity;Immediate prececessor;Time;A;--;8;B;A;4;C;--;10;4;10;12;22;Question 7. 7.Using the;table below compute the slack time for activity D. All times are in weeks.;Activity;Immediate prececessor;Time;A;--;4;B;--;3;C;A;2;D;B;7;E;C,D;4;F;B;5;G;E,F;4;(Points: 1);0;5;3;6;Question 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;13;Question 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;85.0;Question 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 above;Question 14. 14.The work;breakdown structure involves identifying the ________ for each activity.;(Points: 1);time;cost;predecessors;All of the above;Question 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;0.32;Question 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;6;Question 19. 19.Which of;the following is not a concept associated with CPM? (Points: 1);normal time;probability;normal cost;crash cost;Question 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;Time;A;--;4;B;--;3;C;A;2;D;B;7;E;C,D;4;F;B;5;G;E,F;4;(Points: 1);8;12;18;10
