Assume you have a project with 10 activities labeled A-J. De- rive the earliest completion time (or early finish-EF), est completion time (or late finish-LF), and slack for each of the following tasks (begin at time = 0). Which tasks are on the critical path? Draw both a Gantt chart and a network diagram for these tasks, and make sure you highlight the critical path on your network diagram.
