Question
Comparing scales: In an experiment to determine whether there is a systematic difference between the weights obtained with two different scales, 10 m 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 2 15.94 16.57 3 9.00 8.85 4 11.76 11.57 5 24.36 23.88 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 ₁ represent the mean weight on Scale 1 and ₂ = μ₁ −µ₂² 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. Ho: Pa = 0 H₁ <0 This hypothesis test is a left-tailed test. Part: 1 / 5 Part 2 of 5 Find the critical value. Round the answer to three decimal places. If there is more than one critical value, separate them with commas. The critical value(s): 16
