1. State whether each of the following statement is true or false. a) The sequence of activities in a project is depicted by the precedence (0.5 mark) (0.5 mark) relationships. The critical path is the shortest path through the project network. Slack is the amount of time an activity can be delayed without delaying the project. In PERT, three time estimates (optimistic, most likely and pessimistic) provide an estimate of the mean and variance for each activity based on the...
Consider the following project activities:
Calculate the expected time (te) for each
activity.
Draw an Activity on Node (AON) diagram to reflect the flow of
these activities.
Calculate the Early Start (ES), Early Finish (EF), Late Start
(LS), and Late Finish (LF) for each activity.
Calculate the slack for each activity.
Identify all activities on the Critical Path.
Use the data to calculate the probability the project will
finish in 20 weeks (Hint: z-score).

Complete an AON network diagram based on the scenario below. Make sure you respond to each of the following five requirements. Construct an AON diagram using the process described in the videos. Calculate the estimated time for each activity using the three estimates provided. Determine the length of all paths and identify which path is the critical path. During the play, one of the activities on the critical path is delayed by one day. Is this serious? Qualitatively discuss the...
