Draw the network and identify the critical path. Also calculate the earliest-latest starting and finishing times for each activity: \begin{tabular}{|c|c|c|} \hline Activity & Preceding Activity & Time (Weeks) \\ \hline A & & 4 \\ \hline B & & 6 \\ \hline C & A, B & 7 \\ \hline D & B & 8 \\ \hline E & B & 5 \\ \hline F & C & 5 \\ \hline G & D & 7 \\ \hline H & D, E & 8 \\ \hline I & F, G, H & 4 \\ \hline \end{tabular} Identify the critical path for the following network for a small MIS project (all times are in days; network proceeds from node 1 to node 10 ): \begin{tabular}{|c|c|c|c|} \hline \multicolumn{3}{|c|}{ Network } \\ \hline Job Activity & Initial Node & Final Node & Estimated Time \\ \hline A & 1 & 2 & 2 \\ \hline B & 1 & 3 & 3 \\ \hline C & 1 & 4 & 3 \\ \hline D & 2 & 5 & 3 \\ \hline E & 2 & 9 & 3 \\ \hline F & 3 & 5 & 1 \\ \hline G & 3 & 6 & 2 \\ \hline H & 3 & 7 & 3 \\ \hline I & 4 & 7 & 5 \\ \hline J & 4 & 8 & 3 \\ \hline K & 5 & 6 & 3 \\ \hline L & 6 & 9 & 4 \\ \hline M & 7 & 9 & 4 \\ \hline N & 8 & 9 & 3 \\ \hline O & 9 & 10 & 2 \\ \hline \end{tabular}
