This document analyzes crude oil imports into the United States from 1980 to 2006 by country of origin. It presents data showing that total US oil imports, and imports from both OPEC and non-OPEC countries, generally increased over this period. The hypothesis is that there was a steady increase in US oil imports from both OPEC and non-OPEC nations. Graphs are included showing the relationships between total imports and imports from OPEC versus non-OPEC countries over time.

3. Hypothesis H 0 : there is no steady increase of U.S. oil imports from OPEC and none OPEC countries over the years H 1 : There is steady increase in the amount of U.S. oil imports from OPEC and none OPEC nations over the years

4. Rationale Since there is growing incomes of U.S. citizens, high standard of living, demand for energy is expected to also grow, and as such oil imports should increase to meet the rising demand

5. Causal model Rising standard Of living Rising demand for energy Rising household income Rising oil imports
