Problem: Big government? The data file GDP on the text CD and Web site contains the percent of gross domestic product (GDP, the total value of all goods and services a country produces) taken by the government in 82 countries. For example, the government share of GDP is 12.28% in Canada and 10.54% in the United States.

Requirement:

(i) Make a stemplot or a histogram to display the distribution of government share of GDP.

(ii) There are several high outliers. What countries are these? (In the most extreme case, the government took more than the total annual GDP!) What is the overall shape of the distribution if you ignore the outliers?

(iii) Based on your work in (b), give a numerical summary of the center and spread of the distribution, omitting the outliers.

(iv) Some Americans complain about big government and heavy taxes. Where does the United States (10.54%) stand in this international comparison?
