Organize the information above in an activity precedence table showing the activity,precedent, and duration (calculated using the PERT weighted average formula andround to the nearest integer).2. Draw an AON network diagram and calculate its early start, early finish, late start andlate finish times, floats (Free and total) for each activity. Make sure you fully label allnodes in the network.3. Identify the project's critical paths and their lengths.

Project Management Homework-Project Crashing Use the following scenario and data to answer all related questions. A community neighborhood association decided to add a swimming pool to the community activity center. The project is divided into the activities listed in the following table. The activity times and costs, both normal and crashed, are given. To finish the project before the summer season starts, the neighborhood has to make time and cost tradeoffs. If the project needs to be finished in 20 weeks, you are required to formulate a linear programming model to decide about how much to crash for each activity.
