The attached data set shows information about average incomes and percent of returns that were audited by the IRS for select urban areas. Given the data set (see attachment for data and descriptive statistics), I calculated the 95% confidence interval to be +/- 0.107 (sample mean=0.83) for Percent Audited. The question I must answer with this information is: 

Based on this 95% confidence interval, are any of the observed “% audited” in urban areas reported here “unusual”?  Explain.
