2. The length of line AB was measured repeatedly on three different occasions and probable error of each mean value was computed with the following results: 1st measurements = 2111.450± 0.04 ml 2nd measurements= 2111.500± 0.05 m 3rd measurements = 2111.620± 0.02 m Solve the weighted mean of the three measurements conducted.
