[8 points] By using PERT, identify the critical path, calculate the mean and standard deviation of the project completion time.

[2 points] What is the probability that the project is completed within 30 weeks?

[2 points] What is the 90th percentile for the project duration?

[5 points] Simulate the completion of this project 100,000 times assuming that activity times follow a triangular distribution. Estimate the mean and standard deviation of the project completion time. Paste your Crystal Ball output below.

[3 points] By using the simulation output, estimate the probability that the project can be completed within 30 weeks months. What is the 90th percentile for the project duration according to the simulation output? Paste your Crystal Ball output below.
