Project Scheduling with Uncertain Time:

activity	Immediate	Time (weeks)	Most
	predecessor	Optimistic	Probable	Pessimistic
A		3	5	8
B	A	5	7	10
C	A	3	6	10
D	A	2	6	9
E	C, D	1	3	6
F	B, C	3	6	10
G	E, F	2	3.5	7
H	F, G	3	6	10

Be sure to round the expected time to one decimal place.

Be sure to round the variance and standard deviation to 2 decimal places.

Solve the problem and enter your answers to the questions:

1. What are the critical path activities?

2. What is the expected completion time for the project (#of weeks)? (Your answer need to be within 0.1 of the correct answer)

3. What are the variance and standard deviation for the critical path? (Your answers need to be within 0.1 of the correct answer)

4. What is the probability that the project can be completed in more than 30 weeks?
