The accompanying data give the percentage of new vehicles bought with four-wheel drive, region by region for each of 48 regions in a country. The data include the average temperature in that region in January. Complete parts (a) through (d) below. Click the icon to view the data on temperatures and percent four-wheel drive. (a) Do you expect the correlation between these variables to be positive or negative? Explain your choice. O A. The correlation should be negative, because lower temperatures in winter mean more snow and thus more need for four-wheel drive. O B. The correlation should be positive, because higher temperatures in winter mean more snow and thus more need for four-wheel drive. O C. The correlation should be positive, because higher temperatures in winter mean more snow and thus less need for four-wheel drive. O D. The correlation should be negative, because lower temperatures in winter mean more snow and thus less need for four-wheel drive. (b) Draw the associated scatterplot. Does the direction of the association match what you expected to find? Which scatterplot below shows the data? O A. O B. O c.
