Review the resources listed below to prepare for this week's assignment. Before reviewing these resources, read through the assignment instructions so you know what you will be expected to do with this material.

**As you take in your material this week, consider the following questions:**

- What does the central limit theorem say?
- How many samples do I need for the central limit theorem?
- What is the mean of sample means?
- Where does the central limit theorem show up in nature?
- In what ways is it possible to still use the normal distribution to test ideas about non-normal data?
