Consider the following network diagram data for a small project. All duration estimates or estimated times are in days, and the network proceeds from Node 1 to Node 10 : \begin{tabular)[|CCCCC) Whline Activity & Initiai Node & Final Node & Estimated Duration & Total Slack Whline A & 1 & 2 & 2 & \hline B & 1 & 3 & 4 & 1 Whline C & 2 & 4 & 3& Whline D & 3 & 5 & 2 & W Whline E & 4 & 6 & 4 & W \hline F & 5 & 6 & 2 & Whline G & 6 & 7 & 5 & 1 Whline H & 6 & 8 & 3 & \hline I & 7 & 9 & 4 & \hline J & 8 & 9 & 2 & Whline K & 9 & 10 & 5 & W Whline \end{tabular) A) Draw an ADA network diagram representing the project 13 Marks].
