By observing each variable’s corresponding t-statistics and p-values, the results show the statistical significance of each, upon which we conducted tests and modifications to better understand how the variables interact. We can see that gas2002 has the most significant effect of the variables, seen both in a large t-statistic and significant p-value at the 5% level, which is as we had hoped; also by observing the magnitude of the coefficient, giving it an important role in the effect on GDP per capita. We can believe now that it has both a statistical and economic significance.
