NETWORK: PERT 1 Spring 23 Consider the following table: ACTIVITY PREC. ACT. TIME ESTIMATES (days) to tml tp te A --- 2 3 4 B --- 3 5 7 C --- 2 4 6 D A 3 4 5 E B 3 5 13 F C 2 4 6 G D, E, F 4 5 6 1) Construct a PERT network. [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 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 14 days? 6) Between 15 and 17 days?
