Question 28 2.5 pts A 10-year study conducted by the American Heart Association provided data on how age, systolic blood pressure, one for the interaction between age and blood-pressure level and the other for whether the person is a smoker (dummy variable) relate to the risk of strokes. Data from a portion of this study follow. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. # of observations n = 20 # of independent variables (p) = 4 Multiple Coefficient of Determination (R-Square ) 0,53 SSE - 1,357 The following is a partial printout from Excel SUMMARY OUTPUT Regression Statistics Multiple R N/A SUMMARY OUTPUT Regression Statistics Multiple R N/A IR Square 0.53 Adjusted R ?
