2. A new chemotherapy drug is released to treat leukemia andresearchers suspect that the drug may have fewer side effects thanthe most commonly used drug to treat leukemia. The two drugs haveequivalent efficacy. In order to determine if a larger study shouldbe conducted to look into the prevalence of side effects for thetwo drugs, set up a Mann-Whitney U test at the alphaequals .05 level and interpret its results.

                       Number of Reported Side-Effects

Old Drug          0         1         3         3          5

New Drug         0         0         1         2          4

A) We fail to reject H₀, which states the twopopulations are equal at the alpha equals .05 level because thecalculated U value of 16.5 is greater than the criticalU value of 2.

B) We fail to reject H₀, which states the twopopulations are equal at the alpha equals .05 level because thecalculated U value of 8.5 is greater than the criticalU value of 2.

C) We reject H₀ in favor of H₁, whichstates the two populations are not equal at the alpha equals .05level because the calculated U value of 16.5 is greaterthan the critical U value of 2.

D) We reject H₀ in favor of H₁, whichstates the two populations are not equal at the alpha equals .05level because the calculated U value of 8.5 is greaterthan the critical U value of 2.
