This exercise shows that the signed-rank test can be used with paired data. Two gauges that measure tire tread depth are being compared. Ten different locations on a tire are measured once by each gauge. The results, in mm, are presented in the following table. Location Gauge 1 Gauge 2 Difference 3.95 3.80 0.15 3.23 3.30 -0.07 3 3.60 3.59 0.01 4 3.48 3.61 -0.13 3.89 3.88 0.01 3.76 3.73 0.03 3.45 3.56 -0.11 8 3.01 3.02 -0.01 3.82 3.77 0.05 10 3.44 3.49 -0.05 Assume the differences are a sample from an approximately symmetric population with mean µ. Use the Wilcoxon signed-rank test to test H, : µ = 0 versus H : µ # 0.
