Case Study (Ch. 6)
You recommend creating bar graphs in Stat Crunch for the data for Case Study 2 instead of histograms as indicated. The data given in Case Study 2 is summarized in the probability tables. Access to the raw data (watch which option you use when creating your bar graphs). Histograms in StatCrunch don't work very well with summarized data, but the bar graphs work wonders. Also, you will have to use your calculator to calculate mean and standard deviation for at least the first portion. There is not a nice way to calculate these in StatCrunch.
1. Include the shape when describing the distribution.
2. Be though and explain your reasoning.
3. Explain how you would calculate the mean and average.
4. Use the data given or that you found to support your answer.
5. Use data to support your answer. Be thorough.
6. You should include 4-6 summarizing points and a conclusion.
From your analysis (hypothesis test conclusions), does it appear that the mean ages of the artifacts from the ditch, the ditch terminals, the bluestones, and the Y and Z holes is different from Corbin's stated mean age of the ditch, 2950 B.C? Can you use the results from your hypothesis tests to infer the likely construction order of the various Stonehenge structures? Explain.
