Answer 1

The association between smoking and lung cancer may be most similar to +1 Pearson Correlation Coefficient. Smoking is the number one risk factor for lung cancer. In United states, smoking is linked to about 80% to 90% of lung cancer deaths. People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occassionally increases the risk of lung cancer. The more years a person smokes and the more cigareetes smoked each day, the more risk goes up. So this proportion is almost to 100%. That is why the correlation coefficient between lung cancer and smoking is +1.
