- Identify a test statistic to help you assess the evidence against the null hypothesis you developed in the previous module.
- Explain why you have chosen the specific test statistic. Include in your discussion description of the test statistic.
- Summarize your findings by creating a summary graph in which you display your data.
- Discuss the total number of measurements (sample size), the possibility for measurement error, and whether it is large enough to paint an accurate picture.
