I want the solution very quickly within 15 minutes Q3: The ground level of irrigation project is measured at (100x) points out of 1500points. It is found that the mean of the levels equal to 26.59m. If the standarddeviation of ground surface is 2.45m, find the interval of 95% confidence of theground surface level of this project (with and without replacement). How many ofelevations required to measure that gives an error not more than (0.4m) with 95%confidence.X=0.74

Given Data: The mean of the level is X¯=26.59 m The standard deviation of the ground surface is…

If the grid spacing of a finite difference 2D groundwater model with a regular grid (Ay = Ax) is halved how wound that affect the truncation error: O a. No effect as the truncation error is not real. b. It would reduce the truncation error by a factor of four. O c. It would halve the truncation error. O d. It would increase the truncation error by a factor of four. Clear my choice

In a two peg test using model Wild NA2 dumpy level, the following observations were taken: Instrument at C Instrument at D Rod reading on A 1.103 m 0.568 m Rod reading on B 0.991 m 0.289 m Point C is equidistant from A and B and D is 12m from A and 72m from B. What is the true difference in elevation between A and B? With the level in the same position at D, to whatrod reading on B should the line of sight beadjusted? What is the corresponding rod reading on A for ahorizontal line of sight with instrument still at D?
Point A has an elevation of 216.612 m above a vertical datum, and the point B is situated on the opposite sides of a busy twelve-lane highway (44.4 m width). For stability of both point locations are designed one meter away from each edge of the highway. From the measurement, the following results are obtained: Instrument setup at station 1 (A side of highway): Staff reading on A = 0.673 m Staff reading on B = 2.416 m Instrument setup at station 2 (B side of highway): Staff reading on B= 2.992 m Staff reading on A = 1.254 m Based on the description above, choose a proper measurement method used in surveying to realize the elevation at point B? Justify your answer.
