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.
