Chapter 6, Problem 5E(choose chapter or problem)
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.
Assume the differences are a sample from an approximately symmetric population with mean μ. Use the Wilcoxon signed-rank test to test \(H_{0}: \mu = 0\) versus \(H_{1}: \mu \ne 0\).
