Perform a PERT analysis. For all high-level activities in this project, calculate the following:
1. Optimistic time
2. Most likely time
3. Pessimistic time
4. Expected activity time
5. Standard deviation
6. Variance
7. For one date ahead of most likely completion date, calculate Z and hence the probability of completion by that date.
8. For one date behind the most likely completion date, calculate Z and hence the probability of completion by that date.
