Brooke rolled a toy car down a ramp at two different heights. Each height was tested four times.

What can you conclude from the information in the data table?

• The higher ramp height caused the toy car to roll a shorter distance.

• The height of the ramp had no effect on the distance the toy car traveled.

• The shorter ramp height caused the toy car to roll a shorter distance.

• The shorter ramp height caused the toy car to roll a further distance.
