Question

The following distances were estimated by pacing from HW#1 . Compute the distances most probable length and the standard deviation. Discard any measurements which have an error greater than 2o, retain the remaining measurements, start over and recompute the most probable length, the standard deviation and the standard deviation of the mean of the remaining measurements. 776 233 746 762 735 759 739 731 747 778 733 749 736 753 800 770 704 715 786 300 727 741 744 737 745 744

Mean = 711.1538
Std Dev = 132.948
Mean - 2 * Std Dev = 445.2578
Mean + 2 * Std Dev = 977.0499
SE of the mean = 26.0733
There are no data above 2 standard deviations of the mean
