Use the Wilcoxon rank-sum test to test the claim that the two independent samples come from
populations with equal medians. Use the Wilcoxon rank-sum approach to test the claim that
the sample student grade averages at two colleges come from populations with the same
median. The sample data is listed below. Use a 0.05 level of significance, and assume that the
samples were randomly selected. $\begin{array} { l }
\text { College A}&3.2&4.0&2.4&2.6&2.0&1.8&1.3&0.0&0.5&1.4&2.9\
\text {College B }&2.4&1.9&0.3&0.8&2.8&3.0&3.1&3.1&3.1&3.5&3.5\
\end{array}$
