QUESTION 31 A vertical angle was observed 10 times by a total station with the same accuracy. The following readings of the angle were taken: 200 00' 36", 20° 00' 32", 20° 00' 31", 20° 00'37", 200 00' 39", 20° 00' 35", 20° 00' 33", 20° 00'34”, 200 00' 38", 20° 00' 35" Compute the most probable value of the vertical angle and its standard deviation. The result is: O 20° 00' 35"25" O 200 00' 35"-3" O 20° 00' 35"+2" 20° 00'350=1" QUESTION 32 The horizontal distance was measured 10 times by using two types of total stations characterized by a different accuracy. The following readings of the distance were taken: 325.07 m (SD = +2 cm), 325.02 m (SD = +2 cm), 325.11 m (SD = +2 cm), 325.08 m (SD =+2 cm), 325.06 m (SD = 31.5 cm), 325.05 m (SD=+1.5 cm), 325.09 m (SD = +1.5 cm), 325.08 m (SD ==1.5 cm), 325.07 m (SD = +1.5 cm), 325.08 m (SD=1.5 cm). The values in brackets provide the standard deviation (SD) of each measurement. Compute the most probable value of the horizontal distance and its standard deviation. The result is: O 325.07+0.04 m O 325.07+0.03 m O 325.07+0.01 m O 325.07+0.02 m
