Scientists hаve develоped а new fоrensic methоd for estimаting the age of an unidentified crime victim using DNA information in the victim’s blood. To confirm the accuracy of the method, Dutch researchers measured this variable along with the age of 195 volunteers ranging in age from a few weeks to 80 years. The resulting scatterplot (from their paper in Current Biology) is shown below. The researchers put the blood test measure on the horizontal axis because they intend to use it as the explanatory variable to determine age (response variable). NOTE: this measure takes negative values. The least squares regression line is AGE = -33.65 - 6.74 x BLOOD TEST MEASUREwith r-squared = 83.5%. Type a complete interpretation of the slope of the regression equation in the context of this scenario.
