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 385 subjects taking ritonavir-boosted darunavir, 308 achieved a positive result. Of the 385 subjects taking dorovirine, 321 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.) b. Perform a hypothesis test to test whether the proportion of patients who achieve a positive outcome with the current treatment (ritonavir-boosted darunavir) is less than the proportion of patients who achieve a positive outcome with the new treatment (dorovirine). Use a significance level of 0.05. Analyze the results and determine if dorovirine is a more effective treatment for HIV-1 than ritonavir-boosted darunavir. Consider population 1 to be the ritonavir-boosted darunavir with the proportion of positive outcomes p₁, and population 2 to be the dorovirine with the proportion of positive outcomes p2.

Transcribed Image Text: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 385 subjects taking ritonavir-boosted darunavir, 308 achieved a positive result. Of the 385 subjects taking dorovirine, 321 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.)
b. Perform a hypothesis test to test whether the proportion of patients who achieve a positive outcome with the current treatment (ritonavir-boosted darunavir) is less than the proportion of patients
who achieve a positive outcome with the new treatment (dorovirine). Use a significance level of 0.05. Analyze the results and determine if dorovirine is a more effective treatment for HIV-1
than ritonavir-boosted darunavir.
Consider population 1 to be the ritonavir-boosted darunavir with the proportion of positive outcomes p₁, and population 2 to be the dorovirine with the proportion of positive outcomes p2. What are the

Analyze the results. Is dorovirine a more effective treatment for HIV-1 than ritonavir-boosted darunavir? Why or why not?
OA. No; although the decision of the test was to reject the null hypothesis of no difference, it cannot be concluded that one treatment is better than the other-it can only be concluded that they
are different.
OB. Yes, since the decision of the test was to fail to reject the null hypothesis of the proportion from the ritonavir-boosted darunavir group being greater than the proportion of the dorovirine
group.
OC. No, since the decision of the test was to fail to reject the null hypothesis of no difference.
OD. Yes, since the decision of the test was to reject the null hypothesis of no difference.
