Textbook Question
Chapter 17, Problem 9DRQ
Why might a probabilistic estimate of a project’s completion time based solely on the variance of the critical path be misleading? Under what circumstances would it be acceptable?

You have determined the following for a given project:
Expected completion time of the project = 26 weeks
Standard deviation of project completion time = 8
What is the probability of completing the project in more than 32 weeks?
answer as a decimal and take it to four places.
Suppose the due date of the project is 24 months and expected time of completion is 28 months, while the probability of completing it is 90%. What will be the standard deviation?
The following information has been computed from a project:
Expected total project time = T = 62 weeks
Project variance = 81
1- What is the probability that the project will be completed 18 weeks before its expected
completion date?
2- Draw Normal Curve & Analysis your solution with conclusion
