• True

• false

• cant say

_________ are used to represent activity in a network diagram.

• circle

• square

• Rectangle

• arrow

The shortest possible time in which an activity can be achieved under ideal circumstances is known as ________

• a) Pessimistic time estimate

• b) Optimistic time estimate

• c) Expected time estimate

• d) The most likely time estimate

According to the time estimates made by the PERT planners, the maximum time that would be needed to complete an activity is called as __________

• a) The most likely time estimate

• b) Optimistic time estimate

• c) Pessimistic time estimate

• d) Expected time estimate

The difference between the maximum time available and the actual time needed to perform an activity is known as _________

• a) Free float

• b) Independent float

• c) Total float

• d) Slack

Which statistical distribution is assumed by simplified PERT

• beta

• normal

• poisson

• binomial

What does event in CPM & PERT network refers to?

• The occurrence of a delay in the project

• A activity inserted into the network to show a precedence relationship with no passage of time

• beginning or completion of an activity or project e

• The earliest and activity can start

Which statistical distribution is used by PERT to represents time estimates

• chi square

• binomial

• beta

• poisson

Why does activities in the critical path are called critical

• Represent the maximum project completion time

• Can not tolerate any delay in completion

• Represent most expense in terms of resources

• Represent most longest and complex activities of the project
