Use the work breakdown structure (WBS) and activity duration data to do the following:
On a separate sheet, create an activity on node (AON) diagram for this project. Draw it neatly. Identify the critical path.
Calculate the Expected Time (TE) for each activity. All times are in weeks. Round off your answers for TE to two decimal places.
Using the TE time, solve for the early start, early finish, late start, late finish, and slack time for each activity. Show your answers on the diagram.
Calculate the weekly crash costs.
Use the normal probability density function to estimate the probability that the project will be completed within 1 week of its scheduled completion time and to estimate a 90% Confidence interval for the project completion time.
