A large Southeast city is requesting federal funding for a park-and-ride project. One of the requirements in the request application is a
network plan for the design phase of the project. Sophie Kim, the chief engineer, wants you to develop a project network plan to meet
this requirement. She has gathered the activity time estimates and their dependencies shown here.

- 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%.
