In a Normal Approximation to the Wilcoxon Rank Sum Test

Short Answer

In a normal approximation to the Wilcoxon rank sum test, the standardised test statistic is calculated as z = 1.80. For a two- tail test, the p-value is: $\begin{array}{|l|l|}\hline\text { A. } & 0.0359 \\\hline \text { B. } & 0.4641 \\\hline \text { C. } & 0.2321 \\\hline \text { D. } & 0.0718 \\\hline\end{array}$
