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 Ho: HD 0 versus Ha: HD> 0 at significance level 0.01. (Use μD-4-A.) Note: The data below is formatted such that you can copy and paste it into R. Fabric 4 u=c( 36.5, 55.0, 51.5, 38.6, 43.2, 48.8, 25.6, 49.7) A-c28.5,20.0, 46.0, 34.0, 36.5,52.5, 26.5,46.5) 1 2 3 5 6 7 8 Calculate the mean difference and standard deviation Compute the test statistic value. (Round your answer to three decimal places.) p-value - State the conclusion in the problem context. Reject Ho. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions Reject Ho. The data suggests a significant mean difference in breaking load for the two fabric load conditions Fail to reject Ho. The data suggests a significant mean difference in breaking load for the two fabric load conditions Fail to reject Ho. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions You may need to use the t-table to complete this problem
