Activity E has a pessimistic duration of 12 weeks and an optimistic duration of 6 weeks. The formula for calculating the estimated standard deviation in this case is (pessimistic duration – optimistic duration) / 6, which gives us (12-6)/6 = 1. Therefore, the best choice is option C, which represents an estimated standard deviation of 2 weeks.
