CHALLENGE ACTIVITY 3.1.5: Using regression to make predictions. 426930.2891118.qx3zqy7 Jump to level 1 A medical researcher wants to determine how a new medication affects blood pressure. 150 The equation of the regression line is 140 Y = 140 + (-0.0667)X An amount of medication of 120 mg 130 is found to result in a blood pressure . . . Patient systolic blood pressure (in mm Hg) of 130.02 mm Hg. What is the 120 predicted blood pressure? Ex: 7.9 mm Hg 110 Where is the observed value in relation to the regression line? 100 50 100 150 200 250 300 350 Pick v Amount of medication (in mg) An amount of medication of 149 mg is found to result in a blood pressure of 130.06 mm Hg. What is the predicted blood pressure? mm Hg Where is the observed value in relation to the regression line?
