(3) A project was planned using PERT. Its expected completion time was determined to be 55 days. The variance of the critical path is 36. What is the probability the project will be completed in 59 days or more (5 decimal places)? Let X= the project completion time. P(X Please show how you use the Normal Curve Table to obtain your answer in the space below. (4) Perform a project management analysis for the data given below to determine ES, EF, LS, LF, and slack for each activity, the total project completion time, and the critical path.
