At work you have been given a project to complete. The activities and duration for each activity is depicted in the table below: Activity Predecessor Optimistic Most Pessimistic Likely - - + F G Management requires you to determine the feasibility of the project. You are required to: 1. Compute the expected time for each activity as well as the variance for each activity in table form. 1. Construct a precedence diagram for the problem and annotate the ES, EF, LS and LF on the precedence diagram. (11) 1. Find the critical path and determine the expected completion time for the project.
