The following data are from 10 health-planning districts in Vermont. Y is the percentage of live births #2,500 grams. X₁ is the fertility rate for women #17 or $35 years of age. (X₁ is known as the “high-risk fertility rate.”) X₂ is the percentage of births to unmarried women. Compute the regression equation for predicting the percentage of births of infants weighing under 2,500 grams (Y) on the basis of the high-risk fertility rate.
