In an experiment to study the relationship of hypertension and smoking habits, the following data are collected for 180 individuals: Nonsmokers 21 H, 48 NH Moderate Smokers 36 H, 26 NH Heavy Smokers 30 h, 19 NH Where H and NH stands for Hypertension and NonHypertension, respectively. If one of these individuals is selected at random find the probability that the person is (a) experiencing hypertension, giving that the person is a heavy smoker (b) a nonsmoker, giving that the person is experiencing no hypertension
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.
In an experiment to study the relationship of hypertension and smoking habits, the following data are collected for 180 individuals:
Nonsmokers 21 H, 48 NH
Moderate Smokers 36 H, 26 NH
Heavy Smokers 30 h, 19 NH
Where H and NH stands for Hypertension and NonHypertension, respectively. If one of these individuals is selected at random find the
(a) experiencing hypertension, giving that the person is a heavy smoker
(b) a nonsmoker, giving that the person is experiencing no hypertension
