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 11.79 11.83 2 15.22 15.13 3 8.83 9.60 4 11.13 12.10 5 24.59 26.92 6 9.61 10.55 7 14.55 15.01 8 6.99 7.17 9 13.39 14.82 10 20.93 22.45 Send data to Excel Let μ₁ represent the mean weight on Scale 1 and μd=H1-H₂. Can you conclude that the the mean weight on Scale 1 is less than the mean weight on Scale 2? Use the a= 0.05 level of significance and the TI-84 Plus calculator to answer the following. Part 1 of 4 (a) State the null and alternate hypotheses. Ho: "d = 0 H₁: <0 This hypothesis test is a left-tailed Part: 1 / 4 Part 2 of 4 (b) Compute the P-value. Round the answer to at least four decimal places. P-value = .05 X ▼test. S
