Consider a project that has been modeled as follows: $$\begin{array} { c c c } \text { Activity } & \text { Immediate Predecessors } & \text { Duration (hr) } \\\hline \text { A } & \cdots & 7 \\\text { B } & \cdots & 10 \\\text { C } & \text { A } & 4 \\\text { D } & \text { A } & 30 \\\text { E } & \text { A } & 7 \\\text { F } & \text { B,C } & 12 \\\text { G } & \text { B,C } & 15 \\\text { H } & \text { E,F } & 11 \\\text { I } & \text { E,F } & 25 \\\text { J } & \text { E,F } & 6 \\\text { K } & \text { D, H } & 21 \\\text { L } & \text { G,J } & 25\end{array}$$
a.Draw the PERT/CPM network for this project and determine project's expected completion time and its critical path.
b.Can activities E and G be performed simultaneously without delaying the minimum project completion time?
c.Can one person perform A, G, and I without delaying the project?
d.By how much can activities G and L be delayed without delaying the entire project?
e.How much would the project be delayed if activity G was delayed by 7 hours and activity L was delayed by 4 hours? Explain.
