Problem C (Ch3) Assume the activity time estimates and the immediate predecessor information for the activities necessary for the swimming pool construction project are as follows (times in days): 1. Draw the AON network (using the notation we used in class). 2. Compute the expected activity time and the variance for each activity. 3. Compute ES,EF,LS,LF for each activity. What is the expected time to complete the project? What is the critical path? 4. What is the probability that the project can be completed in 25 or fewer days
