Chapter 4.6, Problem 19E

19. Heart disease is a much less problem in France than it is in United States and other industrialized countries, despite a high consumption of saturated fats in France. One theory is that this lower rate heart disease is due to the fact that the French drink more wine. This so-called French paradox heightened an interest in moderate wine drinking. Figure $4.157$ gives data on wine consumption and heart disease for nineteen industrialized countries, including France and the United States, in $1994$.

a. Draw a scatter diagram, find the equation of line of best fit, and find the correlation for wine consumption versus annual deaths.

b. Do the data support the theory that wine consumption lowers the heart disease rate?
