Question

Consider the accompanying data on breaking load (kg/25 mm width) for various fabrics in both an unabraded (U) condition and an abraded (A) condition. Use the paired t test to test: H0: Jug = 0 versus Ha: .120 > [J at significance level 0.01. (Use up : \"UiAJ Note: The data below is formatted such that you can copy and paste it into R. Fabric 1 2 3 4 5 6 7 8 u : c( 36.5, 55.0, 51.4, 30.7, 43.2, 48.8, 25.6, 49.5) A = c( 28.5, 20.0, 46.0, 34.5, 36.0, 52.5, 26.5, 46.5) Calculate the mean difference and standard deviation. d' = 5d = Compute the test statistic value. (Round your answer to three decimal places.) State the conclusion in the problem context. 0 Fail to reject HQ. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions. 0 Reject H0. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions. O Reject H0. The data suggests a significant mean difference in breaking load for the two fabric load conditions. 0 Fail to reject Ho- The data suggests a significant mean difference in breaking load for the two fabric load conditions.
