question 8

Essay

Use the Wilcoxon rank-sum test to test the claim that the two independent samples come from
populations with equal medians. SAT scores for students selected randomly from two different
schools are shown below. Use a significance level of 0.05 to test the claim that the scores for
the two schools are from populations with the same median. $~~ ~ ~ \text { School A }$ $\quad\quad \mid$ $\quad$ $\text { School B }$
$\begin{array}{lll|lll}\hline 550 & 480 & 670 & 460 & 580 & 620 \\400 & 700 & 520 & 380 & 680 & 570 \\540 & 740 & 560 & 660 & 500 & 480 \\360 & 560 & 650 & 600 & 550 &\end{array}$
