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.
