Q1. True or False: There are three steps in Project Management. They are planning, scheduling and controlling.

Q2. True or False: Gantt Chart is a good presentation tool but not a good scheduling tool because it does not take into account the precedence relationships and inter-dependencies among activities.

Q3. True or False: PERT and CPM are both scheduling tools. The only difference between them is that PERT assumes constant activity times while CPM assumes random activity times.

Here is the information about the project:

Activity	Immediate Predecessors	Activity Time
A	N/A	3
B	A	2
C	B	1
D	C	1
E	G, C	2
F	C, D	3
G	B	5
H	F	4

Answer Q4 to Q7 based on this information. Make sure The Earliest Starting Time for Activity F is 7 before you go on.

Q4. True or False: The Earliest Starting Time for Activity E is 6.

Q5. True or False: The Expected Total Project Completion Time is 14.

Q6. True or False: The Critical Path is A-B-C-D-F-H

Q7. True or False: If the activity E is delayed by 3 days, the new total project completion time will be 15 days.

Here is the information about the project:

Activity	Immediate Predecessors	Optimistic Time	Most Likely Time	Pessimistic Time
A	N/A	2	3	4
B	A	1	2	5
C	B	1	2	3
D	A	1	2	3
E	B	4	5	6
F	B, C, D	2	4	6
G	F	2	2	6

Answer Q8 to Q10 according to this information. Use 2 decimal points in the calculation.

Q8. True or False: The mean activity time for activity F is 0.67

Q9. True or False: Make sure the Earliest Starting Time of activity F is 7.33. The mean of the Total Project Completion Time is 14 and the standard deviation is around 1.25.

Q10. Which of the following statement is not true?

1. The probability the project will be shorter than 8 days is almost impossible.
2. The probability that the project will be longer than 12 days is more than 90%.
3. The 85% confidence interval is between 12.20 and 15.80 if we round the numbers to 2 decimal points.
4. If we want to be sure (90% sure) that the project will be completed by the day we promised. We should promise 14 days.
