Scientists have developed a new forensic method for estimating the age of an unidentified crime victim using DNA information in the victim’s blood measured in dCt (in difference of base pairs). To confirm the accuracy of the method, Dutch researchers recorded blood test in dCt and 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 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.
