From 1996 to today, lemon imports from Mexico have increased from 200 metric tons to over 600 metric tons. During this same time period, the total U. S. highway fatality rate has dropped from almost 16% to under 14%. The correlation between
the amount of imported lemons and total U. S. highway fatality rate is -0.98.
Does this suggest that increased lemon imports from Mexico help prevent highway deaths?
Yes, the strong, negative correlation provides evidence that metric tons of lemon imports from Mexico affected the total
U. S. highway fatality rate.
No, it is unlikely that the increase in metric tons of lemon imports from Mexico caused the decrease in the total U. S.
highway fatality rate. Correlation does not imply causation.
No, there was a strong negative correlation between metric tons of lemon imports from Mexico and the total U. S.
highway fatality rate, and fewer highway deaths is a positive change.
Yes, a strong correlation implies that changes in the explanatory variable cause changes in the response variable.
O No, in order to show causation, we need to show that other countries that receive lemons from Mexico also have seen a
decrease in highway fatalities.
