A study for the treatment of patients with HIV-1 was a randomized, controlled, double-blind study that compared the effectiveness of ritonavir-boosted darunavir (rbd), the drug currently used to treat HIV-1, with dorovirine, a newly developed drug. Of the 374 subjects taking ritonavir-boosted darunavir, 310 achieved a positive result. Of the 374 subjects taking dorovirine, 320 achieved a positive result. Complete parts (a) and (b). a. Find the sample percentage of subjects who achieved a positive outcome in each group. The sample percentage of subjects who achieve a positive outcome with ritonavir-boosted darunavir is %. The sample percentage of subjects who achieve a positive outcome with dorovirine is %. (Round to two decimal places as needed.) A study was conducted on the efficacy and safety of varenicline for smoking cessation in people living with HIV. The study was a randomized, double-blind, placebo-controlled trial. Of the 124 subjects treated with varenicline, 16 abstained from smoking for the entire 48-week study period. Of the 123 subjects assigned to the placebo group, 7 abstained from smoking for the entire study period. Complete parts (a) and (b). a. Find the sample percentage of subjects in each group who abstained from smoking for the entire study period. The sample percentage of subjects treated with varenicline who abstained from smoking for the entire 48-week study period is %. The sample percentage of subjects in the placebo group who abstained from smoking for the entire 48-week study period is %. (Round to two decimal places as needed.)
