Let's look at Europe. Refer to the previous exercise. Figure 4.10 gives a scatterplot for the same data for the 48 European countries in the data set. Compare this figure with Figure 4.9, which plots the data for all 181 countries in the data set. Write a paragraph summarizing the relationship between life expectancy and Internet use for European countries with an emphasis on how the European countries compare with the entire set of 181 countries.

(a) Describe the relationship between these two variables.
(b) A friend looks at this plot and concludes that using the Internet will increase the length of your life. Write a short paragraph explaining why the association seen in the scatterplot does not provide a reason to draw this conclusion.
