Question

Quizplus · Accepted Answer

The correlation coefficient between alcohol consumption and driving accidents indicates that they are related. Therefore, if the direction of the relationship is known, a researcher could predict the number of driving accidents a person would have based on the amount of alcohol they consume. Option A is incorrect because the type of car an individual drives is not correlated with alcohol consumption or driving accidents. Option C is incorrect because there is no evidence to support the claim that the number of arrests will increase with the decrease in the number of alcoholic drinks consumed. Option D is incorrect because there is no information provided to suggest that the number of driving accidents a person has will contribute to the number of days spent in jail.
