The following table represents a plan for a project:

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

You can accomplish any one of the following at an additional cost of $2,000. If you will save $1,500 for each day that the earliest completion time is reduced, which of the following actions should be taken, if any?

1.	Reduce job 6 by two days? Yes or No

2.	Reduce job 4 by two day? Yes or NO

3.	Reduce job 9 by two days? Yes or No

e.	What is the probability that the project will take more than 35 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.)
