Question

Suppose that in fact 6% of all adult heterosexuals had more than one sexual partner in the past year (and would admit it when asked).  The National AIDS Behavioral Surveys interviewed a random sample of 2673 people from this population.  Let    p be the sample proportion of the 2673 who have had more than one sexual partner in the past year.  In many such samples, the sample proportion  would be different from one sample to the next.

   p would vary according to (approximately)  the________distribution with mean_______and standard deviation                          .

Explanation / Answer

p would vary according to (approximately)  the________distribution with mean_______and standard deviation                          .

approximately the normal distribution with mean np = 0.06 *(2673)=160.38 and SD = srqt (0.06*0.94*160.38) = 3.007
