2. A new chemotherapy drug is released to treat leukemia and researchers suspect that the drug may have fewer side effects than the most commonly used drug to treat leukemia. The two drug have equivalent efficacy. In order to determine if a larger study should be conducted to look inte the prevalence of side effects for the two drugs, set up a Mann-Whitney U test at the alpha equa .05 level and interpret its results.
