The purpose of this study is to analyze the effect of the two explanatory variables GNP per capita (x1) and the proportion of the population enrolled in elementary school (x2) on the dependent variable infant mortality rate (y). The equation estimated for the White test for the existence of heteroscedasticity is as follows.

u, = - 15.76+0.3810x1i - 4.5641x2; + 0.000005x1; + 0.1328x2; - 0.0050x1X2i 1 = (-0.01) (0.60) (-0.13) (0.87) (0.56) (-0.85) PH = (0.989) (0.556) (0.895) (0.394) (0.581) (0.400) R2 = 0.23
