Question

In an experiment to determine whether there is a systematic difference between the weights obtained with two different scales, 10 rock specimens were weighed, in grams, on each scale. The following data were obtained:


  1 2 3 4 5 6 7 8 9 10
Weight on scale 1 11.14 14.38 8.33 10.50 24.44 9.12 13.46 6.44 12.41 18.35
Weight on scale 2 11.20 14.43 8.39 10.53 24.41 9.16 13.50 6.43 12.44 18.34

Construct a 99% confidence interval for mean difference in weight between the two scales. Interpret the results.
