Maximum Tax Rate
A random sample of 10 Democrats and 10 Republicans were asked what is the largest value (in percentage) that one should be expected to pay as taxes. (Source: Stat Crunch Survey: Responses to Taxes in the U.S. survey. Owner: scsurvey)

a. Test the hypothesis that Democrats have a higher mean than Republicans, using a 0.05 significance level. Assume the data sets are Normal.
b. Create a new data set that repeats each observation in the provided data set. (This means each observation should appear twice.) Test the same hypothesis.
c. Compare the results.
