QUESTION:

Using the Mann-Whitney UTest ?The Mann-Whitney ?U?test is equivalent to the Wilcoxon rank-sum test for independent samples in the sense that they both apply to the same situations and always lead to the same conclusions. In the Mann-Whitney ?U? test we calculate Use the pulse rates listed in Table 13-5 in this section to find the 2 test statistic for the Mann-Whitney ?U? test. Compare this value to the ?z? test statistic found using the Wilcoxon rank-sum test. where
