# Prepare a Presentation

Think about these questions as part of your presentation.

- Within each sample size group, how do your results compare for the five samples? What does this comparison tell you?
- How do your results compare for the three sample size groups?
- How many marbles of each color do you think there are in the jar?

# Challenge Problem

- If the jar held 500 marbles but had 10 different colors of marbles, what do you think the best sample size would be?
