Perform the CPM calculations with the most likely duration of the activities to determine the total project duration and the critical path. b) (20 pts.) For the critical path determined in part a, perform the PERT calculations to determine the probability of being completed within the duration calculated in part a. Note: The optimistic, most likely, and pessimistic activity durations are given in the attached Excel sheet (Question 2). You should write your student ID into the B2 cell to get the durations. Hint: You should use the Z-Table for PERT Calculations' in Moodle to answer this question. B E H J 8 7
