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.
