... B. Regress the dependent variable Y only on X1 (ignore X2 for now). C. Interpret the b1 coefficient you calculated. Explain why it makes sense for the relationship to be positive. D. Calculate and interpret the standard error of the regression. E. Explain why we are not sure that the exact relations ...
