As part of a recent? survey, self-reported? heights, x, and
measured? heights, y, were obtained for males aged 12?16. Use the
Wilcoxon? signed-ranks test to test the claim that the matched
pairs have differences that come from a population with median
equal to zero at a significance level of alpha equals 0.1. Find the
null and alternate hypothesis, test statistic, critival value and
state the conclusion.
