PERT Probabilistic Analysis You are assigned as the new project manager for Sensor Design Project. You are in the processes of developing and analyzing the project’s schedule. Based on the WBS and internal interviews, you outlined the tasks, linkages, and duration range for each task as shown below.

Please answer questions a), b) and c) using this data and the PERT (probabilistic) method

1. Identify the critical path and calculate the mean and standard deviation of the project completion time. Please show your work by inserting Excel analysis
2. Using Normal Distribution Table (included at the end of this Midterm document), what is the probability that the project is completed within 181 days? Please show both the Z value and probability
3. What is the 85^th percentile for the project duration? You can calculate the duration using either normal distribution method or Excel functionality
