A local hospital conducted a study to predict Stroke Risk (y-variable) based on the following x-variables: Age, Weight, and Smoker (1=smokes, 0=does not smoke). Multiple regression results from Excel are shown below. Regression Statistics Multiple R 0.82 R Square 0.67 Adjusted R Square 0.58 Standard Error 9.57 Observations 20 ANOVA   df SS MS F-stat p-value Regression 3 2815.81 703.95 7.68 0.001 Residual 15 1375.14 91.68 Total 18 4190.95         Coefficients Standard Error t Stat P-value Intercept -48.90 37.55 -1.30 0.213 Age 0.27 0.10 2.72 0.016 Weight -0.07 0.07 -1.08 0.296 Smoker 17.09 4.74 3.61 0.003 RESIDUAL OUTPUT Observation Predicted Risk Residuals 1 8.8 -5.8 2 21.3 -13.3 3 14.4 -2.4 4 10.2 2.8 5 16.7 -1.7    Question:  Interpret (precisely) the coefficient on Age in the regression model above.

What classification of amplifier is this? What is its conduction angle? How good is its linearity compared to the other classifications? How good is its efficiency compared to the other classifications? What would be the most ideal input impedance for this circuit? (Assuming impedance matching not important) What would be the most ideal output impedance for this circuit? (Assuming impedance matching not important)
