PROBLEM 7: Situation: A surveying Instructor sent all the 40 students in his class out to measure a distance between two points marked on a runway. The students working in groups of four came up with 10 different measurements as follows: 920.45, 921.05, 921.65, 920.25, 920.15, 921.86, 921.95, 920.45, 821.15, and 921.35 meters. Assuming these values are equally rellable and that varlations result only from accidental errors. Determine the probable error of the mean.

PROBLEM 7:
Situation:
A surveying Instructor sent all the 40 students in his class out to measure a distance between two points
marked on a runway. The students working in groups of four came up with 10 different measurements as
follows: 920.45, 921.05, 921.65, 920.25, 920.15, 921.85, 921.95, 920.45, 821.15, and 921.35 meters.
Assuming these values are equally reliable and that variations result only from accidentali errors.
Determine the probable error of the
mean.
