A ---- 6 9 12
B ---- 4 8 12
C A 5 6 7
D A 2 4 6
E B,D 4 7 10

What is the expected completion time of the project?
Select one:
a. 34
b. 15
c. 20
d. 25

What is the probability of completing the project given in 22 days?
Select one:
a. greater than 95%
b. greater than 75% but less than or equal to 85%
c. greater than 85% but less than or equal to 95%
d. less than or equal to 75%.

Solution Summary

Solution depicts the steps to calculate expected completion time. It also calculates the and desired probability value.

Determine theexpectedcompletiontime and variance for each activity, theexpectedcompletiontime and variance for the overall project completiontime, and answer questions a, b, and c below.
2. Determine theexpectedcompletiontime and variance for each activity, theexpectedcompletiontime and variance for the overall p

Using the information provided in the table, the network diagram and theexpected project completiontime = 39 weeks (see attachment):
The critical path is A-B-D-G-H.
(a) Calculate the probability of completing the project in 36 weeks.
P(project ? 36) =
(b) Calculate the probability of completing the project in 40 w

Using PERT, Harold Benson was able to determine that theexpected project completiontime for the construction of a pleasure yacht is 22.7 months and the project variance is 9.
What is the probability that the project will be completed in 20 months?
What is the probability that the project will be completed in 26 months?

Task time estimates for the modification of an assembly line at Jim Goodale's Carbondale, Illinois, factory are as follows:
ACTIVITY TIME (IN HOURS) IMMEDIATE PREDECESSORS
A 6.0
B 7.2
C 5.0 A
D 6.0

A project is being analyzed using PERT. Theexpectedcompletiontime of the project is 70 weeks with a standard deviation of 5 weeks. Assume the project completiontime is normally distributed. If the due date of the project is to be set to there is only a 20% chance of being late (and an 80% chance of finishing on time), what s

A project was planned using PERT with three time estimates. Theexpectedcompletiontime of the project was determined to be 40 weeks. The variance of the critical path is 9.
What is the probability that the project will be finished in 46 weeks or less?
A. 2%
B. 73%
C. 98%
D. impossible to determine with this informati

General Motors is planning a new ad campaign targeted at aging Boomers who seek roominess, comfort and elegance.
Based on past experience, Task #1 usually takes days 52. If things do not go as planned, the task will take 74 days. If things go very well, Task #1 can be completed in 40 days.
Task #2 usually takes 87 days. Ta
