Medical researchers believe that there is a relationship between smoking and lung damage. Data were collected from smokers who have had their lung function assessed and their average daily cigarette consumption recorded. Lung function was assessed in such a way that higher scores represent greater health. The researchers believe that the relationship between these variables may be influenced by the number of years for which the person has been a smoker. Requirements: 1.
