The following represents a project that should be scheduled using CPM:

ACTIVITY	IMMEDIATE PREDECESSORS	TIMES (DAYS)
		a	m	b
A		1	5	9
B		1	2	3
C	A	3	5	7
D	A	1	4	10
E	B	1	2	3
F	C,D	1	2	12
G	D,E	1	6	8
H	F,G	2	3	8

2. What is the critical path?

   multiple choice

   • A-C-F-H

   • A-D-G-H

   • A-D-F-H

   • B-E-G-H

3. What is the expected project completion time?

   Note: Do not round intermediate calculations. Round your answer to 3 decimal places.

4. What is the probability of completing this project within 20 days?

   Note: Use Excel's NORM.S.DIST function to find the correct probability for your computed Z value. Do not round intermediate calculations. Round Z value to 2 decimal places and final answer to 4 decimal places.
