- From the survey, the following readings were observed successively with a leveling instrument. check the arithmetic calculations by the following two methods.• rise and fall method• height of collimation methodDetermine: (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 300.713mThe difference in elevation between two ground points was measured by each of three field parties using different kinds of leveling instruments. The results are as follows: 1st Party, DE = 18.45 m +0.04 m; 2nd Party, DE = 18.40 m ± 0.05 m; and 3rd Party, DE = 18.48 m ± 0.03 m. Determine the most probable difference in elevation between the two ground points. %3D
