Consider a project that has been modeled as in the table below. Part a) Draw the PERT/CPM network for this project and determine the project’s expected completion time μP and its critical path. Part b) Suppose the standard deviations of the activity durations are σA = 2, σB = 1, σC = 0, σD = 2, σE = 3, and σF = 0. Then please estimate the standard deviation of the overall project’s standard deviation σP . Part c) Suppose for the standard Normal random variable Z, we know P[−1 ≤ Z ≤ +1] ' 68%, P[−2 ≤ Z ≤ +2] ' 95%, and P[−3 ≤ Z ≤ +3] ' 99.7%. Then, approximately what time T is one for which there is only a less than 2.5% chance for the completion time to beat (be shorter than)? *Please answer a-c and type your work and answers or write them neatly please* Thank you

A project is scheduled to complete in six months duration. There are two activities in the project. The actual cost of Activity 1 is SAR 300,000 and that of Activity 2 is SAR 200,000. The planned value of these activities is SAR 280,000 and 150,000 respectively. On reviewing, the current project status is Activity 1 is 100% completed and Activity 2 is only 75% completed. (i) Perform the earned value calculations of the above project scenario and fill the given table. (ii) What do you infer about the project schedule and cost based on your calculations?
