For the network below:
1. Calculate T-E and Variance for each activity. Assume the durations have 95% certainty (i.e. the range from optimistic to pessimistic durations covers 95% of all possible durations).
2. Calculate the expected duration of the network. Do not use Crystal Ball.
3. What is the probability the network will take no more than 23 days? Use the Z-table or Excel’s NORM.DIST formula, not Crystal Ball. Be sure to show all work.
