Independent Random Samples from Two Populations Are Shown in the Table

Essay

Independent random samples from two populations are shown in the table. $\begin{array}{c}\hline\text { Sample 1 }\quad\text { Sample 2 }\\\begin{array}{ccc}\hline 11 & 14 & 9 \\3 & 12 & 5 \\16 & & \\\hline\end{array}\begin{array}{ccc}\hline 19 & 17 & 10 \\22 & 18 & 8 \\14 & 25 & \\\hline\end{array}\end{array}$


Use the Wilcoxon rank sum test to determine whether the data provide sufficient evidence to indicate a shift in the locations of the probability distributions of the sampled populations. Use $\alpha = 0.05$
