The hypothesis that men in high stress jobs have an increased risk of developing coronary heart disease was tested during an 18-year follow-up study from 1965-1983 of a group of 7,909 men of Japanese ancestry in Hawaii. Of the 7,909 men who completed the first examination at baseline, 4,673 were free of prevalent coronary heart disease (CHD), stroke, and cancer for the duration of the study, while 3,236 had incident CHD. Of the 4,579 men with higher stress jobs, 1,440 of them developed CHD; of the men with lower stress jobs, 1,796 of them developed CHD.
13) What is the study design? Please be as specific as possible.
14) Generate a 2x2 contingency table:
15) Calculate the cumulative incidence of CHD for those exposed to higher stress jobs:
16) Calculate the cumulative incidence of CHD for those unexposed to higher stress jobs:
17) Calculate the relative risk of CHD for the high stress group as compared to the low stress group.
18) Calculate the risk ratio of CHD for the low stress group as compared to the high stress group.
19) Interpret your results for both #17-18 in one sentence:

Can bacteria reproduce in a way such that when you start out with two bacteria, you get five bacteria? why or why not? * a. yes, because bacteria reproduce sexually, and can produce any number of offspring, just as humans do. b. no, because bacteria grow at an exponential rate. c. no, because when bacteria reproduce, they split into two parts, and two bacteria splitting would result in four bacteria.
