Statistical theory based approach expects you to follow the standard PERT solution process to identify the mean and variability measures. For the Monte Carlo simulation based approach, the data file is attached as PERT - ex ante data. \begin{tabular}{|c|c|c|c|c|c|} \hline Activity & Optimistic & Most Likely & Pessimistic & Predecessor & Critical Path \\ \hline A & 17 & 29 & 47 & & Yes \\ \hline B & 6 & 12 & 24 & A & Yes \\ \hline C & 16 & 19 & 28 & A & \\ \hline D & 13 & 16 & 19 & B & Yes \\ \hline E & 2 & 5 & 14 & C & \\ \hline F & 2 & 5 & 8 & D, E & Yes \\ \hline \end{tabular} Please compare the duration estimation based on the following two approaches.
