In the United States , there is a strong relationship between education and smoking : well-educated people are less likely to smoke . Does a similar relationship hold in France ? Here is a two-way table of the level of education and smoking status ( nonsmoker , former smoker , moderate smoker , heavy smoker ) of a sample of 458 French men aged 20 to 60 years . The subjects are a random sample of men who visited a health center for a routine checkup . We are willing to consider them an SRS of men from their region of France . Smoking Status Education Nonsmoker Former Moderate Heavy | Total Primary school 54 56 42 35 187 Secondary school 39 41 25 34 139 University 51 27 36 18 132 ( 2 ) Fill in the blanks in the table below with the conditional probabilities of smoking status given the level of education .
