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 12.02 12.28 15.51 15.71 9.00 8.93 11.34 11.26 25.29 25.75 9.79 10.09 14.41 14.87 7.05 7.11 13.52 13.70 21.12 20.70 Send data to Excel Let , represent the mean weight on Scale 1 and Ha = H1 - H2. Can you conclude that the the mean weight differs between the Scales? Use the a=0.05 level of significance and the TI-84 Plus calculator to answer the following. Part: 0 / 4
