Question
In the united states, there has historically been a strong relationship between smoking and education, with well-educated people less likely to smoke. To examine whether this pattern has changed, a sample of 459 men was selected at random from those who had visited a health center for a routine check-up over the course of the past year. Education is classified into three categories corresponding to the highest level of education achieved, and smoking status is classified into four categories. The proportion of former smokers with a university education is: A. 0.34. B. 0.15. C. 0.22. D. 0.57.Explanation / Answer
as we can see that number of people who are former smokers with a university education is (28+43=71) out of 459
therefore probability =71/459=0.15
option B is correct
