The death rate per 100,000 for lung cancer is 7 among non-smokers and 71 among smokers. The death rate per 100,000 for coronary thrombosis is 422 among non-smokers and 599 among smokers. The prevalence of smoking in the population is 55%. On the basis of the relative risk and etiologic fractions associated with smoking for lung cancer and coronary thrombosis, which of the following statements is most likely to be correct? A. Smoking seems to be equally causally related to lung cancer and coronary thrombosis. B. Smoking seems much more likely to be causally related to lung cancer than to coronary thrombosis. C. Smoking seems much more likely to be causally related to coronary thrombosis than to lung cancer. D. No comparative statement is possible between smoking and lung cancer or coronary thrombosis. E. Smoking does not seem to be causally related to either lung cancer or coronary thrombosis.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
