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.

A) We fail to reject Ho, which states the two populations are equal at the alpha equals .05 level
because the calculated U value of 16.5 is greater than the critical U value of 2.
B) We fail to reject Ho, which states the two populations are equal at the alpha equals .05 level
because the calculated U value of 8.5 is greater than the critical U value of 2.
C) We reject H, in favor of Hi, which states the two populations are not equal at the alpha
equals .05 level because the calculated U value of 16.5 is greater than the critical U value of 2.
D) We reject Ho in favor of Hı, which states the two populations are not equal at the alpha equals
05 level because the calculated U value of 8.5 is greater than the critical U value of 2.
