In a Wilcoxon Signed Rank Sum Test, the Test Statistic $D \neq 0$

question 75

Short Answer

In a Wilcoxon signed rank sum test, the test statistic is calculated as T = 75. If there are n = 15 observations for which $D \neq 0$ , and a two-tail test is performed at the 5% significance level, then: $\begin{array}{|l|l|}\hline \text { A. } & \text {we reject the null hypothesis. } \\\hline \text { B. } & \text {we don't reject the null hypothesis. } \\\hline \text { C. } & \text { the test results are inconclusive.} \\\hline \text { D. } & \text { we perform a parametric test.} \\\hline\end{array}$
