In exercise
From the Statistical Abstract of the United States, we obtained data on percentage of gross domestic product (GDP) spent on health care and life expectancy, in years, for selected countries. Those data are provided on the WeissStats CD. Do the required parts separately for each gender.

b. Obtain the linear correlation coefficient.
c. Interpret the value of r in terms of the linear relationship between the two variables in question.
