Compute the expected time of each activity using the Beta probability distribution.2. Calculate the incremental crash cost per week for each activity.3. PERT-Cost Network showing normal time, crash time and incremental cost per week of the activities.4. Identify the critical path.5. What is the project's expected completion time and cost?6. Assume that the company wants to complete the project in 26 weeks. What crashing decisions do you recommend to meet the desired completion time at the least possible cost?7. How much will be the total project cost after the crashing decisions?
