Scenario: Imagine you are a Math Committee Review member at the local elementary school. You have been asked to review a curriculum change for 5th graders in math.

1. Include a brief background of the problem and why it is important. From this information, identify a clearly written research question.
2. State the null and alternative hypothesis (in both words and statistical notation) needed to address the research question.
3. Describe the type of data needing to be collected and the techniques you would use.
4. Choose which statistical test you would use to conduct the study. Support your method with research.
5. How might you report your findings? Explain the potential ethical dilemmas.
