Answer:
The standard deviation on the critical path = 0.834
Step-by-step explanation:
Variance of activity A (
) = 0.33
Variance of activity B (
) = 0.67
Variance of activity C (
) = 0.33
Variance of activity D (
) = 0.17
Thus the standard deviation on the critical path (
) =
+
+
+ ![V^2_{4}](https://tex.z-dn.net/?f=V%5E2_%7B4%7D)
=
+
+
+
= 0.6956
= 0.834
The standard deviation on the critical path = 0.834
