[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 Te and ES, EF, LF, LS, state TIMES on the network. Find the slack of each activity and clearly identify the Critical Path. 3) Find the average completion time ( Xbar) and (s Sigma), the standard deviation, for the project- round off the standard deviation to the nearest hundredth: two decimal places. 4) What is the completion time at 95% Confidence Interval? 5) What is the likelihood of this project being completed in more than 8 days? 6) What is the likelihood of this project being completed BETWEEN 9 and 11 days? ANSWERS: RECAP COMPLETED NETWORK with: Drawing, Te, Times, and CP clearly shown on network. CP: xbar: Sigma: CI: 95% [ ____ to _____] ND: Pd>7: P8>d >7
