A sociologist examines the relationship between the poverty rate and several socioeconomic factors.For the 50 states and the District of Columbia (n = 51),he collects data on the poverty rate (y,in %),the percent of the population with at least a high school education (x₁),median income (x₂,in $1000s),and the mortality rate per 1,000 residents (x₃).He estimates the following model as y = β₀ + β₁ Education + β₂ Income + β₃ Mortality + ε.The following ANOVA table shows a portion of the regression results. The coefficient of determination indicates that __________. A) 14% of the variation in the poverty rate is explained by the regression model. B) 14% of the variation in the regression model is explained by the variation in the poverty rate. C) 86% of the variation in the poverty rate is explained by the regression model. D) 86% of the variation in the regression model is explained by the variation in the poverty rate.
