A researcher used stepwise regression to create regression models to predict Birth-Rate (births per1000) using five predictors: Life-Exp (life expectancy in years), InfMort (infant mortality rate), Density (population density per square kilometer), GDPCap (Gross Domestic Product per capita), and Literate (literacy percent). Interpret these results. BirthRates2

Regression Analysis-Stepwise Selection (best model of each size)

153 observations

BirthRate is the dependent variable

p-values for the coefficients
