Using the regression results in column (3): Workers in the Northeast earn $ 0.10 more per hour than workers in the West, on average, controlling for other variables in the regression. (Round your response to two decimal places.) Workers in the South earn $ 0.28 less per hour than workers in the West, on average, controlling for other variables in the regression. (Round your response to two decimal places.) Do there appear to be important regional differences? A. Yes, because workers in the Northeast earn significantly more than workers in the South. B. No, because workers in the Midwest earn more per hour than workers in the Northeast, while workers in the South earn less per hour than workers in the West. C.
