Comparing scales: 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: Specimen Weight on Scale 1 Weight on Scale 2 1 11.90 12.28 15.94 16.57 9.00 8.85 4 11.76 11.57 5 24.36 23.88 6. 9.88 10.09 7 14.14 13.93 8 7.05 6.85 9 13.39 13.82 10 20.16 20.90 Send data to Excel Let u, represent the mean weight on Scale 1 and u, =µ, -µɔ. Can you conclude that the mean weight on Scale 1 is less than the mean weight on Scale 2? Use the a=0.01 level of significance. Part 1 of 5 (a) State the null and alternate hypotheses. 0 = Pri :°H
