Task
a. Draw the activity network diagram for this problem (either AON or AOA)
b. Determine the Expected Time and Variance for each activity.
c. Show the activity schedule (ES, EF, LS, and LF) as well as slack (in table).
d. Determine and state the critical path for this project. This must be based on your work in (c) and not by inspection.
e. What are the expected time and the variance of the project?
f. What is the probability the project will be completed in less than 32 weeks?
g. What time should be set such that there is a 95% chance of completion?
