During lab last week, we used 1 bag of beans. We took the mass of 3 of the beans in the bag. Next, we took the mass of the empty bag and subtracted that from the total mass of the bag full of beans. We averaged the mass of the 3 beans that we measured to find the approximate mass per bean in the bag. Finally, we divided the total weight of just the beans in the bag by the average mass of the 3 beans that we massed individually.

What was the sample size in this experiment?

• 1

• 3

• around 600

• 10

We use ________ as the base unit to measure the length of an object in the metric system.
