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. $ \quad $$\text { Program I }$ $ \quad $ $ \quad \mid$ $ \quad $$\text { Program II }$
