 Examine the County Complete database. Pick three states in the same area of the country as yours, one of which is your home state. Determine one variable that was not included in your workshop two analysis. Complete the following analysis:

1. Determine the mean, median, mode, standard deviation, and variance for the counties in all three states. How are they different? The same?
2. Assess each of your three variables for normality.
3. Determine a 95% confidence level for each of the three states for the mean value of counties.
4. Compare the confidence level of your home state to the actual value for your home county. Is it within the confidence limit you have calculated? If not, what could be factors causing it to be an outlier?
5. Write a short report that includes the results of your analysis. Include whatever graphs or statistical output you may have generated in answering these questions along with a short explanation of your analysis.
