(You may use MSP or draw an AOA or AON network by hand.) b) Using Excel, calculate the expected time (TE) and variance for each activity. c) Using the expected times, find the path with the longest expected time. What is the expected time to complete this path? (Use the analytic method.) d) Find the probability that the critical path will be completed in 38 days or less. e) Are there any serious sources of merger problems? What are they? Calculate the probability of finishing the project on or before Day 38 when merger considerations are included. d, e 10 12
