State the critical path(s). What is the expected project completion time? hours. What is the slack time of activity F? hours. What is the late finish of activity C? If activity D were delayed by 2 hours, what effect would this have on the project time? If activity B were delayed by 2 hours what effect would this have on the project time? Name an activity that you could be sure would be on the critical path even if you didn't know what the activity times were for any of the activities (but precedence relationships remained the same as shown here).
