An instrument operator can discriminate a target with a precision of half a second or arc.
A) compute the angular error for a total of ten observations to the same target.
B) the same operator measures the angle to the target as 73 degrees 41' 53" the rest of the observation listing only the seconds are 55", 50", 48", 53" 49" 58" 50" 54" and 46". Compute the mean in degrees minutes and seconds and the standard deviation in seconds for the observations.
