Students from Molly's middle school wanted to know if the amount of milk that a cow produces is affected by the cow's age. The students measured the milk from four cows that were 2,4,6,
and 8 years old. They measured how much milk each cow produced each day for four days.
The cows were the same breed, lived on the same farm, and were fed the same amount and
type of hay.
