3. Suppose researchers are interested in estimating the prevalence of HIV in a population of adolescent intravenous drug users determined to equal 9.4% in the population. In order to estimate the prevalence of the disease, the researchers need to randomly sample from the population of potential participants in their study. Suppose the researchers are able to randomly sample 127 participants, and find that 29 are co-infected with the diseases of interest. A) Can we approximate this distribution with the normal? Why or why not? B) Create a Z score for this sample. C) What is the probability of observing the sample that was collected?
