## What you’ll learn to do: Conduct a hypothesis test or construct a confidence interval to investigate a difference between two population means. Interpret results in context.

### LEARNING OBJECTIVES

• Under appropriate conditions, conduct a hypothesis test about a difference between two population means. State a conclusion in context.
• Construct a confidence interval to estimate a difference in two population means (when conditions are met). Interpret the confidence interval in context.
