Which relationships could have a negative correlation? check all that apply. number of hours on video games and test scores speed of a car and minimum stopping distance average running speed and total race time adult’s head circumference and age outside temperature and amount of a heating bill

A) Number of hours on video games and test scores
If more number of hours are spent on the video games, then the test scores will be less. This indicate that these two are negatively correlated.

B) Speed of a car and minimum stopping distance
If the speed of a car is more, it will need a larger minimum stopping distance. This indicates that these two are positively correlated

C) Average running speed and total race time
If the total race time is more, the average running speed will be less. This indicates that these two are negatively correlated

D) Adult’s head circumference and age
Adult's head circumference do not change much with the age. So these two does not seem to be correlated

E) Outside temperature and amount of a heating bill
If outside temperature is lower, the amount of heating bill will be higher. So these two are negatively correlated.

Therefore, the correct options to this question are:
1) number of hours on video games and test scores
2) average running speed and total race time
3) outside temperature and amount of a heating bill
