The U.S. Census Bureau serves as the leading source of quantitative data about the na- tion's people and economy. The following crosstabulation shows the number of house- holds (1000s) and the household income by the highest level of education for the head of household (U.S. Census Bureau website, 2013). Only households in which the head has a high school diploma or more are included.

An economic organization tracks summary statistics of various countries. These include GDP (gross domestic product per capita) and trade balances (measured as a percentage of GDP). Exporting countries tend to have large positive trade balances. Importers have negative balances. The data are shown in the accompanying table. Formulate the SRM with GDP as the response and Trade Balance as the explanatory variable. Complete parts (a) through (c) below. Click the icon to view the data table. (a) Country X reported the highest positive balance of trade, 24.2% of GDP and per capita GDP equal to $63,000. Fit the least squares equation both with and without country X and compare the results. Does the fitted slope change by very much? Find the least squares equation without country X. Complete the equation below.

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
