(c) Obtain the plus four 95% confidence interval for the difference between the proportion of resprouting shrubs in dry areas when treated with fire or not. Interpret your of interval in context. V 20.23 Treating AIDS. The drug AZT was the first drug that seemed effective in delaying the onset of AIDS in HIV-positive patients. Evidence for AZT's effectiveness came from a large randomized comparative experiment. The subjects were 1300 HIV-positive volunteers who had not yet developed AIDS. The study assigned 435 of the subjects at random to take 500 milligrams of AZT each day, and another 435 subjects to take a placebo. (The others were assigned to a higher dose of AZT, but we will compare only the first two groups.) At the end of the study, 38 of the placebo recipients and 17 of the AZT recipients had developed AIDS.
