Regression analysis was applied between demand for a product (y) and the price of the product (x), and the following estimated regression equation was obtained. ŷ = 130 − 20x Based on the above estimated regression equation, if price is increased by 5 units, then demand is expected to by units.

In a simple linear regression, if the correlation coefficient between x and y is 0.60, then the coefficient of determination is . This means % of the variations in y are explained by x.

For a simple linear regression, if the correlation coefficient between the dependent and independent variable is 0.9, the percentage of variations in the dependent variable explained by the independent variable is %.
