The force acting on a beam was measured 5 times under the same operating conditions. This process was repeated by 3 observers, resulting in 3 sets of data. The means of these data sets were: Mean 1- 7, Mean 2. 6, Mean 3- 6 The corresponding standard deviations were: 3.2, 2.1, and 2.5, respectively. Compute the Pooled Mean of the 3 data sets.
