A teacher uses two different CAI programs to remediate a randomly selected group of students. Results for two
independent samples on a standardized test are listed in a table below. At the 0.05 level of significance, use the
Wilcoxon rank-sum test to test the hypothesis that the sample results are from populations with equal medians. $$\begin{array} { | l | l | }
\hline { \text { Program I } } & { \text { Program II } } \
\hline 60756163 & 66896877 \
\hline 86696470 & 84808187 \
\hline 728259 & 78739193 \
