- Indicate the critical path.
1-3-6-8-9-11
1-2-5-8-9-11
1-4-7-10-11
- What is the expected completion time for the project? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
- 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?
- Reduce job 5 by two days.
Yes
No
- Reduce job 3 by two days.
Yes
No
- Reduce job 7 by two days.
Yes
No
- What is the probability that the project will take more than 30 days to complete? (Use Excel’s NORMSDIST() function to find the correct probability for your computed Z-value. Other than the expected completion time you entered in part c above, do not round intermediate calculations. Round “z” value to 2 decimal places your final answer to 4 decimal places.)
There is an 82 percent chance the project below can be completed in X weeks or less.

B 3 3 3
C 1 3 5
D 6 8 10
E 4 7 10

What is X? (Do not round intermediate calculations. Round your answer to the nearest whole number.)
The following represents a project that should be scheduled using CPM:
TIMES (DAYS)

A-C-F-H
B-E-G-H
A-D-G-H
- What is the expected project completion time? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
- What is the probability of completing this project within 16 days? (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.)

You have just been assigned to oversee a series of projects. Functional areas will loan you personnel for each project, and separate project managers will be responsible for separate projects. These project managers will report to you. Which project management structure is being used?
Multiple Choice
Pure project
Task force
Matrix project
Functional project
PERT
You have just performed a CPM analysis and have found that more than one path through the project network has zero slack values. What can you conclude?
Multiple Choice
You have incorrectly performed the analysis.
You have multiple critical paths.
Only one path is optimal.
More than one path is optimal.
The project will not be completed by the desired time.
A simple project listing of five activities and their respective time estimates are presented here:
