Consider the following project. Use activity times as the most likely time for determining the critical path. Use the optimistic and pessimistic times (together with activity times) to determine expected completion time limits

a. Draw PERT Chart with earliest and latest start and finish times/activity. Fill in the slack time in the table for each activity. Show the slack time for each path for all paths and show Critical Path (CPM) and CPM time.

b. What is the expected time for 68, 95 and 99 percent Confidence Interval (CI) for the project?

c. Show the (ID 0=55%, ID1=60%, ID 2=70%, ID 3=80%, ID 4=85%, ID 5=50%, ID 6=65%, ID 7=75%, 8=99.5%, ID 9=97.5%), Confidence Interval for the project (use section 7.4.3. page 225 for parts 2/3) for only one percentage corresponding to your ID, not all percentages.
