Suppose that, for a certain population, we can predict log earnings from log height as follows: •−a person who is 66 inches tall is predicted to have earnings of $30,000. •−every increase of 1% in height corresponds to a predicted increase of 0.8% in earnings. •−the earnings of approximately 95% of people fall within a factor of 1.1 of predicted values. give the equation of the regression line and the residual standard deviation of the regression.
