Using your same activities from Question 1, complete a PERT time chart. You may use educated guesses for the optimistic, most likely, and pessimistic times, but expected time must be calculated. (4 points) Activity Immediate Optimistic Most Pessimistic Expected Predecessors Likely time A B D E F G H End OI 7. Use the following chart to answer the below questions: (6 points, 1.5 per letter question) civity Predecessors Optimistic time Most Likely Time Pessimistic Time Expected time A 1 3 4 B 2 4 5 A 2 3 5 D B 1 3 4 E 2 3 6 F 2 4 5 G 8 D, E 4 6 5 ww 6 st E G te ww Use the following chart to answer the below questions: (6 points, 1.5 per letter question) zivity Predecessors Optimistic time Most Likely Time Pessimistic Time Expected time A 1 3 4 B 2 4 5 A 2. 5 3 4 D B 3 1 3 2 6 E 5 4 F 2 C 8 6 4 G 4 2. 1 H mo un on C DI D, E F G H END a.
