Answer:

- number of hours on video games and test scores

- average running speed and total race time

- outside temperature and amount of a heating bill

Step-by-step explanation:

1. number of hours on video games and test scores (negative correlation - as you spend more hours on video games, test scores might decrease)

2. speed of a car and minimum stopping distance (positive correlation - as the distance to the next stop increases, the speed of the car should increase)

3. average running speed and total race time (negative correlation - as you run for longer, your speed should decrease)

4. adult’s head circumference and age (positive correlation - as your age increases, your head size increases, too)

5. outside temperature and amount of a heating bill (negative correlation - as temperature increases, the heating bill decreases)
