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 verysmall amount of time and should be treated as a numericzero in the analysis.a. Based on the critical path, find the probability ofcompleting the office renovation project by 39 days.b. Find the date by which you would be 90 percent sure ofcompleting the project.
Given the following network and activity time estimates, determine:
The expected time and variance for each activity
The critical path. This must be based on your calculations of the start and finish times and not by inspection.
The expected project completion time, variance and standard deviation
The probability that the project will be completed in 20 weeks or less
