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:

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
