The text presents a set of differential leveling notes outlined in Table 2. The task involves three main parts:a. **Determining the Elevation of Each Station**: - Calculate the elevation for each station using the given data.b. **Adjusting Elevation with Known Reference**: - The elevation of BM 132 is given as 153.236 meters. - The total length of the level run is 780 meters, with an equal spacing between each station. - Adjust the elevation at each station to account for any errors, ensuring the error is evenly distributed. Provide sample calculations to demonstrate this adjustment.c. **Evaluating Accuracy Ratio**: - Assess the accuracy ratio of the survey. - Verify if the survey meets the accuracy requirement, which is an error ratio of less than 1/3,000.**Table 2 Explanation**:- The table contains the following columns: Station, BS (Backsight) [m], HI (Height of Instrument) [m], FS (Foresight) [m], and Elevation [m].- Stations: BM 130, TP 1, TP 2, TP 3, BM K110, TP 4, BM 132.- Given data includes values for BS, HI, FS, and Elevation for each station. The elevation for BM 132 is noted as 153.236 meters.- To calculate missing elevations using the BS and FS values, apply the formula: \[ \text{Elevation at next station} = \text{Elevation at current station} + \text{BS} - \text{FS} \]These steps and calculations will facilitate the determination of accurate elevations and ensure the survey complies with the specified accuracy standards.

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.
