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 () = + + +
= + + +
= 0.6956
= 0.834
The standard deviation on the critical path = 0.834
