Consider the following table: 1. Construct a PERT network. (2 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 times, the slack of each activity, and the critical path. (I point ea.) Find the completion time () and the standard deviation () for the project - round off the standard deviation to the nearest hundredth: two decimal places. (1 point ea) 3. What is the completion time at 68% and 95% confidence levels? ( 1 point ea.) 4. What is the likelihood of this project being completed in more than 18 days? (I point) 5. Between 14 and 15 days? (1 point)
