(20 points) (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. (15 points) 3. Find the completion time (x) and the standard deviation (o) for the project-round off the standard deviation to the nearest hundredth: USE two decimal places. (20 points) 4. What is the completion time at 95% confidence levels? (15 points) 5. What is the likelihood of this project being completed in less than 18 days? (15 points) 6. Between 18 and 20 days?
