The following table represents a plan for a project: Use Appendix G.

		TIMES (DAYS)
JOB NO.	PREDECESSOR JOB(S)	a	m	b
1		2	3	4
2	1	1	7	13
3	1	4	5	12
4	1	3	3	9
5	2	3	4	5
6	3	1	2	3
7	4	2	9	10
8	5, 6	1	3	5
9	8	2	4	12
10	7	3	4	5
11	9, 10	3	10	11

b.	Indicate the critical path.
	1-3-6-8-9-11 1-2-5-8-9-11 1-2-5-8 1-4-7-10-11

c.	What is the expected completion time for the project? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Expected completion time

days

d.	You can accomplish any one of the following at an additional cost of $1,500. If you will save $1,000 for each day that the earliest completion time is reduced, which of the following actions should be taken, if any?

1.	Reduce job 3 by three days.
	Yes No

2.	Reduce job 7 by two days.
	Yes No

3.	Reduce job 8 by four days.
	No Yes

e.	What is the probability that the project will take more than 33 days to complete? (Use Excel's NORMSDIST() 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.)
