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
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.
A solved PERT problem is detailed in the table below. The expected time and variance values and the critical activities are given in the table below. Answer the following questions by filling the blanks (WRITE YOUR ANSWERS TO 2 DECIMAL PLACES. DO NOT ROUND UP OR DOWN):
