Consider the Following Project Network -In the Previous Project Network, the Critical Path Activities Are

Consider the following project network. Time estimates are in weeks. Complete the following table and questions : $$\begin{array} { | c | l | l | l | l | l | l | l | } \hline \text { Activity } & \text { Time } & \text { Earliest Start } & \text { Earliest Finish } & \text { Latest Start } & \text { Latest Finish } & \text { Slack } & \text { On Critical Path? } \\\hline \text { A } & & & & & & & \\\hline \text { B } & & & & & & & \\\hline \text { C } & & & & & & & \\\hline \text { D } & & & & & & & \\\hline \text { E } & & & & & & & \\\hline \text { F } & & & & & & \\\hline\end{array}$$ $\begin{array}{|c|c|c|c|c|c|c|c|}\hline \text { Activity } & \text { Duration } & \text { ES } & \text { EF } & \text { LS } & \text { LF } & \text { Slack } & \begin{array}{c}\text { On } \\\text { CP? }\end{array} \\\hline \text { A } & 2 & 0 & 2 & 0 & 2 & 0 & \text { yes } \\\hline \text { B } & 4 & 2 & 6 & 2 & 6 & 0 & \text { yes } \\\hline \text { C } & 5 & 6 & 11 & 6 & 11 & 0 & \text { yes } \\\hline \text { D } & 4 & 11 & 15 & 11 & 15 & 0 & \text { yes } \\\hline \text { E } & 6 & 2 & 8 & 9 & 15 & 7 & \text { no } \\\hline \text { F } & 7 & 15 & 22 & 15 & 22 & 0 & \text { yes } \\\hline\end{array}$
