A meteorologist notices a negative association between temperature and number of automobile accidents. Which of the following is a true statement? When the temperature drops, there may be more accidents. It is very likely that automobile accidents cause a decrease in temperature. On a scatterplot of accidents vs. temperature, the least-squares line would be approximately horizontal. Days with higher-than-average temperatures generally correspond with higher-than-average numbers of accidents. It is very likely that the increase in cars driving safely on the road releases greenhouse gases that increase the air temperature.
