Draw an activity-on-node network diagram for the following project, including the estimated time for each activity:

Activity	Optimistic Time (weeks)	Most likely weeks	Pessimistic Time weeks	Prdecessor time weeks
A	2	3	4	-
B	4	5	12	-
C	4	6	8	A,B
D	3	7	11	C
E	7	9	14	D
F	1	2	3	C
G	9	11	13	F
H	4	8	12	C
I	2	6	16	G,H
J	1	4	10	I

b) What is the critical path, expected duration, and variance of the project?

c) Using the expected times you calculated, which activities have slack and how much?

d) What are the chances that you can finish this project in 34 days?

e) If I gave you an extra resource s (say 5 person-weeks of work) what would you do

with them?
