4.30 What is the probability that among 10 true hyperten- sives at least 50% are being treated appropriately and are complying with this treatment? 4.31 What is the probability that at least 7 of the 10 hyper tensives know they have high blood pressure? 4.32 If the preceding 50% rates were each reduced to 40% by a massive education program, then what etfect would this change have on the overal mortality rate among true hypertensives; that is, would the mortalty rate decrease and, il 80, what percentage of deaths among hypertensives could be prevented by the education program?
Hypertension A national study found that treating people appropriately for high blood pressure reduced their overall mortality by 20%. Treating people adequately for hypertension has been dit- ficult because it is estimated that 50% of hypertensives do not know they have high blood pressure, 50% of those who do know are inadequately treated by their physicians, and 50% who are appropriately treated fail to follow this treat- ment by taking the right number of pilis. 4.30 What is the
