The National AIDS Behavioral Surveys interviewed a sample ofadults in cities where AIDS is most common. This sample included803 heterosexuals who reported having more than one sexual partnerin the past year. We can consider this an SRS of size 803 from thepopulation of all heterosexuals in high-risk cities who havemultiple partners. These people risk infection with the AIDS virus.Yet 304 of the respondents said they never use condoms.
Find a 95% confidence interval for the population proportionthat never use condoms?
