Discussion 1. Which observation variable contributes the most to the error in the computed elevation of P? The σBSA contributes the most to the error in the computed elevation of P, it has the largest value. 2. What is the standard deviation of the computed elevation of P from station A when you combine all the contributions? The standard deviation of the computed elevation of P from station A is 0.068 ft. 3. What is the computed elevation of P using the observations at point A? What is the computed elevation of P using the observations at point B?

Unformatted text preview: At point A, the elevation of P is 707.518 ft. At point B, the elevation of P is 707.431 ft. 4. What is the difference in the two values and is it acceptable? What is the average elevation of P? The average elevation of P is 707.475 ft. The difference is between observation at point A and average is 707.518 - 707.475= 0.043< 0.068 which is acceptable. 5. Assume the standard deviation of the computed elevation of P is the same from station A and station B. What is the standard deviation of the average elevation of P? The standard deviation of the average elevation of P is 0.048 ft....
