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.
