15.15 Wine and heart disease. Drinking moderate amounts of wine may help prevent heart attacks. Let's look at data for entire nations. Table 15, 1 gives data on yearly wine consumption (liters of alcohol from drinking wine, per person) and yearly deaths from heart disease (deaths per 100,000 people) in 19 developed countries in 2001. a. Make a scatterplot that shows how national wine consumption helps explain heart disease death rates. b. Describe in words the direction, form, and strength of the relationship. c. The correlation for these variables is r=0.645. Why does this value agree with your description in part (b)? Table 15.1 Wine consumption and heart disease "Laters of aleohol rrom arankang wane, per person. 6 Deaths per 100,000 people, ischemic heart disease. 15.18 Wine and heart disease. Table 15.1 gives data on wine consumption and heart disease death rates in 19 countries in 2001. A scatterplot (Exercise 15.15) shows a moderately strong relationship. The least-squares regression line for predicting heart disease death rate from wine consumption, calculated from the data in Table 15.1, is y=115.868.05x Use this equation to predict the heart disease death rate in a country where adults average 1 liter of alcohol from wine each year and in a country that averages 8 liters per year. Use these two results to draw the least-squares line on your scatterplot
