2. mean ages of the various sites. 
3. Do these confidence intervals support Corbin’s claim?
4. Can you use these confidence intervals to infer the likely construction order of the various Stonehenge structures? Explain.
5. Which statistical technique, hypothesis testing or confidence intervals, is more useful in assessing the age and likely construction order of the Stonehenge structures? Explain.
6. Discuss the limitations and assumptions of your analysis. Is there any additional
7. information that you would like to have before publishing your findings?
8. Would another statistical procedure be more useful in analyzing these data? If so, which one? Explain. Write a report to Corinn Dillion detailing your analysis.
