3 point estimates
|A project manager made 3-point estimates on a critical path and found the following results:
Assuming ±3 sigma precision level for each estimate, what is the standard deviation of the allover path?
|App. 4.2 days|
|App. 5.2 days|
|App. 6.2 days|
|You can not derive the path standard deviation from the information given.|
Can you pleaseexplain how?
