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 identify the Critical Path. 3) Find the average completion time (x xbar) and (o 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 68% and 99% Confidence Interval? 5) what is the likelihood of this project being completed in more than 26 days? 6) what is the likelihood of this project being completed in les than 24 days
