Analyze the provided project schedule using PERT, calculating ES, EF, LS, LF, and Slack for each activity and identifying the critical path.

Here are the solutions to your questions:

1. Project Schedule Analysis

• a) Create a PERT network diagram to represent the project schedule above. To create the PERT network diagram, we first calculate the Early Start (ES), Early Finish (EF), Late Start (LS), Late Finish (LF), and Slack for each activity.

  Activity Calculations:

  \begin{array}{|c|c|c|c|c|c|c|c|} \hline Activity & Predecessor(s) & Duration & ES & EF & LS & LF & \textbf{Slack
