Aim Hypothesis :  Your aim is to use the data to investigate which factors are important in determining the level of air pollution. Some data transformation is likely to need investigation.

The purpose of this model ( scatterplot ) is to  demonstrate any relationship between So₂  ( the response ) and the variables. There is a  strong correlation ( association)  between manufacturing and population, this may be explained by higher populations levels  being found where there is more work , and the manufacturing process output  found  and manufacturing has the highest SO₂ levels.
