An angle has been measured six individual times with the following results: a.) 46° 21' 45"; b.) 46° 22' 10"; c.) 46° 22' 05"; d.) 46° 22' 00"; e.) 46° 21' 45"; f.) 46° 21' 55". What is the most probable value of the angle? A. 46° 21' 45" B. 46° 21' 50" C. 46° 21' 57" D A60 22' 00"

5. The following data were obtained by stadia observations: Vertical angle = + 9°25', upper and lower stadia hair readings are 2.352 and 0.995 m., respectively. The stadia interval factor is known to be 99.00 and C is 0.381 m. The height of the instrument above the instrument station (point A) is 1.496 and rod reading is taken at 1.589m. Determine the following: the horizontal stadia distance а. b. the vertical stadia distance c. the elevation on the point where the rod was held

P Give suitable examples as you discuss how errors in surveying activities are classified. The three angles of a triangle were measured using a triangulation scheme, and their mean values were reported as 50° 48′ 18′′, 64° 2036", and 64° 5100".Each of these means has a standard deviation of 4 according to analysis of each set.The angles were measured again at a later time under better lighting, resulting in mean values of 64° 20′ 39", 64° 50' 58", and 50° 48' 20" prime prime Each value's standard deviation was 2 n. Determine the most probable values of the angles

A level loop was run and the raw elevations in Table 2 were calculated based on backsights and foresights. A plan view of the loop is shown in Figure 2. The true elevation of BM1 is 195.00 ft. Adjust the elevation of each station such that the error is evenly spaced. Show sample calculations of your work. Also determine the accuracy ratio of the survey.
