Problem: In five trials of walking along a 90 m course on a relatively level ground, a student for survey party counted 51, 52.5, 51.5. 52.5, and 51.5 strides. He then started walking an unknown distance XY in four trials which were recorded as follows: 88.5, 89, 88, and 87 strides. Determine the following: a) Pace factor of the student b) Length of line XY c) Percentage error of the measurement if the taped length of XY is 150.50m d) Relative precision of the measurement.
