SEATWORK ON PROJECT MANAGEMENT 1. Ross Hopkins, president of Hopkins Hospitality, has developed the tasks, durations, and predecessor relationships in the following table for building new motels.

Draw the AON Network. B. Solve for the expected time and variance. Round off to a whole number. C. Based on the calculation of the estimated times, determine the critical path. D. Solve for the slack time per activity. 2. Consider the data given in the following table and give what is asked.

Create a Gantt Chart using the normal time. B. Create an AON and AOA network diagram. C. Determine the critical path. D. Determine the crash cost per period. E. Suppose the owner of the company wants to limit the project time within 11 days, which activity/ies should you crash? SEATWORK ON PROJECT MANAGEMENT 1.
