You are managing a project to rebuild a bridge over the River Nile in Egypt.  There are four activities left on the critical path. Activity A has a duration uncertainty of 30 days.  Activity B has a duration uncertainty of 24 days.   Activity C has a duration uncertainty of 12 days.  Activity D has a duration uncertainty of 12 days. What is our Standard Deviation for each activity? (A,B,C,D)
