2. A new chemotherapy drug is released to treat leukemia and researchers suspect that the drug may have fewer side effects than the mostconnnonlyused drug to treat leukemia. The two drugs have equivalent efcacy. _I_n__o_1_'_d_e_r__t_g determine if a larger study should be conducted to look into the prevalence of side effects for the two drugs, set up a Mann-W'hitney U test at the alpha equals .05 level and interpret its results.

We reject H0 in favor of H], which states the two populations are not equal at the alpha equals .05 level because the calculated U value of 10 is greater than the critical Uvalue of 2. [ardessa Smith HLTH 501-'WK 7' 0f 101'2 l b. We reject H0 in favor of H1, 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 Uvalue of 2. c. 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 Uvalue of 2. d. We fail to reject Ho, which states the two populations are equal at the alpha equals .05 level because the calculated U value of 10 is greater than the critical Uvalue of 2
