A distance AB is measured 5 times as 610.03, 610.01, 610.05,610.04 and 610.02 meters. The measurements were given weights of 3,2,1,2,and 3 respectively by the head tapeman. Determine the weighted mean for distance AB. Also, determine what difference results if later judgement revises the weights to 2, 3, 1,3, and 2.
