What is the critical path for this project? 36 The critical pattern is C-F-H-K-M 87 38 2. What is the slack on each activity? 9 30 11 12 13 3. What is the probability of completing the critical path in 80 weeks? 14 (80-78)/ square root (37.78)=0.325 15 The probability of completing the critical path in 80 weeks 0.6274 or 62.74%. 36 17 18 4. What completion time would give you a 99% confidence of completing the project on-time? 19 The time needed is 78+2.32*square root of (37.78)=92.25 weeks 50 51
