Answer(a):

Answer(b):

Activity	Optimistic (O)	Most probable (M)	Pessimistic (P)	Expected Time (O+4M + P)/6	Variance [(P -O)/6]2
A	1.5	2	2.5	2	0.03
B	2	2.5	6	3	0.44
C	1	2	3	2	0.11
D	1.5	2	2.5	2	0.03
E	0.5	1	1.5	1	0.03
F	1	2	3	2	0.11
G	3	3.5	7	4	0.44
H	3	4	5	4	0.11
I	1.5	2	2.5	2	0.03

Answer(c):

Activity	Earliest start	Latest start	Earliest Finish	Latest Finish	Slack	Critical Activity
A	0	0	2	2	0	Yes
B	2	2	5	5	0	Yes
C	0	1	2	3	1
D	2	3	4	5	1
E	5	10	6	11	5
F	6	11	8	13	5
G	5	5	9	9	0	Yes
H	9	9	13	13	0	Yes
I	13	13	15	15	0	Yes

The critical path followed - End

Estimated completion time = 2+3+4=4+2 = 15 Weeks

Answer(d):

We calculate the variance sum of all critical path activities

0.03 (A) +0.44(B)+0.44(G) + 0.11 (H) + 0.03 (I) = 1.05

For probability of 0.99 , from the distribution table We find that Z = 2.56

Z = ( T .15)/1.05^0.5 = 2.56

T = 15 + 2.56 * 1.05^0.5 = 17.62 Weeks.
