1. Activities on the critical path exhibit positive slack times.
TRUE FALSE
2. The variance of project completion time equals the variances of all activities in the project.
TRUE FALSE
3. The expected activity time is the average of an activity’s optimistic and pessimistic times.
TRUE FALSE
4. Dummy activities are found in activity-on-arc (AOA) convention PERT/ CPM network models.
TRUE FALSE
5. The dummy activity has an expected time of zero by definition.
TRUE FALSE
6. Early start time ( ES ) is computed from right to left (backward pass)
TRUE FALSE
7. The project-group approach extends little or no formal authority to the project coordinator.
TRUE FALSE
8. The expected completion time of a task (activity) is approximated by the normal probability distribution.
TRUE FALSE
9. CPM was developed for a project for which task (activity) times were uncertain.
TRUE FALSE
10. With probabilistic PERT, we are able to calculate the probability of finishing the project on a particular day or week.
TRUE FALSE
11. The 3 time estimates employed in PERT are optimistic time, average time, and pessimistic time.
TRUE FALSE
12. In PERT, the early start time for a task is equal to the latest of the early finish times of all of its immediate predecessors.
TRUE FALSE
13. PERT stands for Probabilistic Evaluation and Review Technique.
TRUE FALSE
14. In PERT, we assume project completion time can be modeled by the normal probability distribution.
TRUE FALSE
15. In PERT, the variance in project completion time is equal to the variance of the most time-consuming task (activity) on the critical path.
TRUE FALSE
