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 2. 2. CPM(Points : 1)

assumes we do not know ahead of time what activities must be completed. assumes that activity time estimates follow the normal probability distribution. is a deterministic network technique that allows for project crashing. is a network technique that allows three time estimates for each activity in a project.

Question 3. 3. Which of the following statement about project crashing is false?(Points : 1)

The crash cost is greater than or equal to the normal cost of an activity. The crash time is less than or equal to the normal time to complete an activity. Reducing the time of an activity on the critical path automatically reduces total project duration. It may not be possible to crash a particular activity.

Question 4. 4. 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.

What due date should be set?(Points : 1)

Question 8. 8. In a PERT network, the latest (activity) start time is the(Points : 1)
