In a population-based cohort study, an entire community was interviewed regarding smoking habits and then followed for one year. All lung cancer deaths were ascertained and the following data were available:
•Fifteen (15) lung cancer deaths occurred among 24,500 smokers
•Two (2) lung cancer deaths occurred among 10,500 non-smokers
Calculate the following and interpret your results in each case.

1.Calculate the proper measure of association of smoking and lung cancer.
The relative risk is used to measure the association of smoking and lung cancer.
Using the Rater Ratio to estimate the RR
= 15/100000 =7.5
2/100000

Relative Risk=1
The relative risk is greater than 1 which shows an association between exposure and disease and there is an exposure between smoking and lung cancer.

2.Calculate the population risk difference.
Risk Difference = AR = I of smoker – I of non- smoker
Smoke Lung Cancer Total
Yes No
