Consider the following project where times are in weeks

Table 1. Activity times and predecessors

ACTIVITY	PREDECESSOR	OPTIMISTIC TIME	MOST LIKELY TIME	PESSIMISTIC TIME	VARIANCE
A	-	5	12.5	23
B	-	9	12	15
C	A,B	4	6	11
D	B	3	4.5	6
E	A	4	8	12
F	C	5	8	11
G	E,F	5	6	10
H	D,F	2	3	4
I	G,H	3	3	3
J	I	2	3	7

Required

1. Determine the Expected Time of each activity.
2. Determine the activity schedule (ES, EF, LS, and LF) as well as slack. (10 marks)
3. Determine and state the critical path for this project. This must be based on your work in c) and not by inspection.
4. What are the expected time, variance and standard deviation of the project?
5. What is the probability that the project will be completed in 35.5 weeks?

Please do it in word document... so the workings can be clearer. Thanks in advance
