A study published in Health Magazine in 2010 suggested that a combination of high blood pressure and binge drinking have an incr
eased risk of having a stroke or heart attack. As part of a study that followed 6100 South Korean men aged 55 and over for two decades, men with high blood pressure who binge drank even occasionally had doulbe the risk of dying from a storke or heart attack when compared to those who didn't drink and had normal blood pressure. What type of study is this?
Retrospective study is a study that compares two groups of people; those with disease or condition under study and a very similar group of people who do not have the disease or condition.
Here they are compring those men with high blood pressure who drank and those with no high blood pressure and don't drink.
18% of 420 is 75.6. Multiply that by 63 to get 4762.8. 420 multiplied by 63 equals 26460. 26460 plus 4762.8 is 31222.8. 31222.8 divided by 63 is 495.6. So the answer is $495.60 per year.
