Hello students, today we will discuss about this question.
00:04
In this question we have given two cohort studies that were conducted the first involved and assignments of the relationship between the cigarette smoking and the incidence of the lungs cancer.
00:19
For cigarette smoker, the lungs cancer increase rate that was i .e.
00:27
Is equal to 200 per one double.
00:31
Now for non -smoker, that is for smoker.
00:37
Now for non -smoker, the cancer incidence rate, that is, i -0 is equal to 25 per 100 -3 -0 for non -smoker.
00:50
Now, the lung cancer incidence rate in the entire population, that is, it, that is, 100 per 100 ,000 -3 -0, for entire population.
01:08
And the second study involves an assignment of the relationship between cigarette smoking and incidence of coronary heart disease for a cigarette smoker, a coronary heart disease incidence rate that was i .e.
01:25
That is equals to 500 per 100 -0 -3 -0 for smoker.
01:33
It is for lungs.
01:36
Here i now for non -smoker that is i 0 that is 250 per 100 -300 for non -smoker and here in overall population the coronary heart rate it that is equals to 300 per so here we can say for entire population it is for a coronary disease so here we need to find in the part a, what is the risk of developing a coronary heart disease in the second study? that is equal to question mark...
