Consider the accompanying data on breaking load (kg/25mm width) for various fabrics in both an unabraded condition and an abraded condition. ("The Effect of Wet Abrasive Wear on the Tensile Properties of Cotton and Polyester-Cotton Fabrics," J. Testing and Evaluation, 1993: 84-93). Use the paired t-test, as did the authors of the cited article, to test at significance level.01.
H_o: U_d=0
H_a: U_d>0
Fabric
1 2 3 4 5 6 7 8
U 36.4 55.0 51.5 38.7 43.2 48.8 25.6 49.8
A 28.5 20.0 46.0 34.5 36.5 52.5 26.5 46.5
Find the critical value.
