Question 1 of 4

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)

A

A : 30, B : 24, C : 12, D : 12

B

A : 7.5, B : 6, C : 3, C : 3

C

A : 5, B : 4, C : 2, D : 2

D

A : 25, B : 16, C : 4, D : 4
