An experiment finds that runners with the longest legs complete a mile run in less time. Identify the relation between leg length and time of a mile run. Select the correct answer below: Leg length and time of a mile run are positively correlated. Leg length and time of a mile run are negatively correlated. An increase in leg length causes a decrease in the time of a mile run. A decrease in the time of a mile run causes a decrease in leg length.
