NETWORK: PERT Consider the following table: ACTIVITY PREC. ACT TIME ESTIMATES (days) to tmi tp ta A 2 3 4 2 4 6 C 2 4 6 D A 3 4 5 E B 2 5 8 F C 2 4 6 G D, E, F 1 2 3 1) Construct a PERT network. PLEASE SHOW ALL WORK [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 O 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
