Tor F1. Regular CPM gives one duration for an activity while PERT requires a range of dates. Tor F 2. The "most likely" duration and the "expected" duration are two names for the same variable. Tor F3. PERT requires the knowledge of the distribution each activity follows. Tor F 4. Higher standard deviation means higher uncertainty in the duration (of an activity or a continuous path of activities). Tor F 5. It is possible that the path calculated by the regular CPM as the longest path (hence, the critical path), not be the same path picked by PERT as the "most critical path". Tor F 6. In LSM, if the second activity has much higher production rate than the first one, then we apply the distance (or time) buffer to the end of the activities
