Researchers are concerned about the prevalence of hypertension among a population of elderly patients at a cardiovascular clinic aged 45-60. Suppose the prevalence of hypertension in the group is actually quite high at 38%. Assume that a sample of 14 participants is collected. Use a binomial distribution to solve for the following. a) What is the expected number of participants in this age range to report hypertension? (1 point)[16a] (Example answer #.##)   b) What is the probability associated with finding 7 responses indicating hypertension? (1 point)[16b] (Example answer .####)   c) What is the probability associated with finding between 5 and 8 responses indicating hypertension? (1 point)[16c] (Example answer .####) (hint x is 6 and 7)

HIV/AIDS patients are regularly monitored for their CD4 counts in order to make sure that antiretroviral therapies are effective. Suppose the distribution of CD4 counts in a population is approximately normal with µ=299 and σ=45. a) HIV patients are defined as moving into the AIDS stage of their disease course after their CD4 counts are ≤ 200. What proportion of patients in this population is suffering from an AIDS diagnoses? (1 point)[15a] (Example answer .####)  b) HIV positive patients maintaining a CD4 count over 400 can frequently carry on regular lives with complications mostly limited to medication side effects. What proportion of patients in this population is considered healthy? (1 point)[15b] (Example answer .####)
