Is it just me or does anyone else notice some errors with some of the Wilcoxon sign rank test problems. I couldn't figure out why my test statistic was well out of range from the statistical table. When I checked the solutions I found my differences didn't match some of them and appeared it's because of typos in the data set given in some of the problems.
