Question:
12.97 Based on data from 63 counties, the following model was estimated by least squares:
yn = 0.58 - .052x1 - .005x2 R2 = .17 1.0192 1.0422 where yn = growth rate in real gross domestic product x1 = real income per capita x2 = average tax rate, as a proportion of gross national product The numbers in parentheses under the coefficients are the estimated coefficient standard errors.
