Compare two weighing techniques (direct weighing and weighing by difference) and determine if there is a significant difference in the two methods at 95% confidence level. Perform statistical analysis to quantitatively describe the results. 1.)Perform  Q-test (at 95% confidence level) for the lowest values and highest of the two weighing methods.  2.) Compute for the following statistical parameters for the two weighing techniques: mean, standard deviation, RSD, range, coefficient of variation and confidence interval. What are the errors in the results, if there are any?
