Textbook Question
Chapter 7, Problem 26P
Consider the office renovation project data in Table 7.16. A“zero” time estimate means that the activity could take a very small amount of time and should be treated as a numeric zero in the analysis.
- Based on the critical path, find the probability of completing the office renovation project by 39 days.
- Find the date by which you would be 90 percent sure of completing the project.

Consider the office renovation project data in Table 7.16. A “zero” time estimate means that the activity could take a very small amount of time and should be treated as a numeric zero in the analysis.a. Based on the critical path, find the probability of completing the office renovation project by 39 days.b. Find the date by which you would be 90 percent sure of completing the project.
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
you can solve it on table and i will copy it
