[NOTE: This is the most crucial part of the exercise. Make sure you have the correct network before proceeding to the next sections.) 2) By using ES, EF, LF, LS, find the slack of each activity and the critical path. 3) Find the completion time (Xbar) and the standard deviation (o) for the project - round off the standard deviation to the nearest hundredth: two decimal places. (ONLY COMPUTE SIGMA ON THE Critical Path] 4) What is the completion time at 95% confidence level? 5) What is the likelihood of this project being completed in more than 15 days? 6) Between 13 and 14 days?
