Please, I need help because I have no idea how to do any of these.
11. Building a backyard swimming pool consists of nine major activities. The activities and their immediate predecessors are shown. Develop the project network.
For question number 12, you need to refer to question number 11. Also the first picture is for #11 and second picture(image) is for #12
12. Assume that the activity time estimates (in days) for the swimming pool construction project in Problem 11 are as follows:
a. What are the critical activities?
b. What is the expected time to complete the project?
c. Based only on the critical path, what is the estimated probability that the project can be completed in 25 or fewer days?

- Use the Program Evaluation and Review Technique to represent the project in an activity network. In conjunction with the Critical Path Method, use the activity network to find the shortest time possible to complete the project, to identify the critical jobs in the project, and to determine the earliest and latest that each activity can start and finish without making the project completion longer.a=1, b=1, c=6, d=5, e=2, f=5; andab=1x1=1, bc=1x6=6, cd=6x5=30, de=5x2=10, ef=2x5=10, af=1x5=5.arrow_forwardSuppose you are the project manager for the following project: First, draw a network diagram for the project. Determine the critical path and slack times for all of the tasks. This completes your plan for the project schedule. During project execution, you become aware of the need to change the duration of Task 4 to five days. Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, if any, effects do these changes have on your project? What would have happened if you had not been monitoring the status of the project?arrow_forwardThe following represents a project that should be scheduled using CPM a. Complete the table b.
