# A linear project is split into six identical activities, each having a, m and b durations of 4, 8 and 10 days, which results in the standard deviation of the duration for the complete project being X1 days. As an alternative attempt at project planning, the earlier- split six activities are clubbed as (1st and 2nd), (3rd and 4th) and (5th and 6th), thus needing to consider only three(now-modified) activities; and the standard deviation of the duration for the complete project is now reported as X2 days. What will be the ratio X2/X1
