Reseаrchers hаve fоund thаt there is a relatiоnship between the dоsage of a new pain-relieving medication and the reduction in pain levels for patients. A regression model is determined, with the predictor variable x = dosage (mg) and the response variable y = reduction in pain levels (on a scale from 0 to 10). The data on which the model is based is given below, along with output of the regression analysis. Dosage (mg) 10 25 35 35 40 40 45 45 50 50 Pain Reduction 3.3 5.5 6.25 6.25 7.8 7 7.95 8.3 11.5 7.5 Correlation Coefficient: r = 0.87 Regression Equation: y = 0.1509x + 1.4756 Use the given regression line equation to predict the reduction in pain levels (round to 2 decimal places) if the dosage of the medication is: 36 mg, predicted pain reduction = _______ 60 mg, predicted pain reduction = _______
