Determine: (a) The probable error of the mean in Taping Operation 1. (b) The probable error of the mean in Taping Operation 2. (c) The combined most probable measurement of the frontage, in meters. Answer these questions using this taping scenario. Two surveying tapes were used in measuring the frontage of an open field. The resulting measurements are as follows: Taping Operation 1 Taping Operation 2 300.977m 300.761m 300.415m 300.772m 299.743m 300.776m 299.994m 300.713m
