Independent Random Samples from Two Populations Are Shown in the Table

Essay

Independent random samples from two populations are shown in the table. $\begin{array}{c}\begin{array}{lll}\hline\text { Sample } 1\\ \hline 11 \quad 14 \quad 9 \\3 \quad 12 \quad 5 \\16 & &\\\hline \end{array}\begin{array}{lll}\hline\text { Sample } 2\\ \hline 19 \quad 17 \quad 10 \\22 \quad 18 \quad 8 \\14 \quad 25 \\\hline \end{array}\end{array}$
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 α = .05.
