Title: Medical researchers conducted a study designed to evaluate the relationship between blood pressure ... Post by: Infinitez on Feb 19, 2023 Medical researchers conducted a study designed to evaluate the relationship between blood pressure (y), age (x1), and cholesterol (x2). They proposed a linear model. A total of 126 individuals were randomly sampled, and blood pressure, age, and cholesterol were recorded for each. The regression summary appears here: The regression equation is Blood Pressure = 45.5 + 1.03 Age + 0.032 Cholesterol Predictor Coef SE Coef T P Constant 45.54 50.73 0.90 0.371 Age 1.02866 0.03920 26.24 0.000 Cholesterol 0.0323 0.4071 0.08 0.937 S = 5.30434 R-Sq = 85.0% R-Sq(adj) = 84.7% Analysis of Variance Source DF SS MS F P Regression 2 19600.5 9800.2 348.32 0.000 Residual Error 123 3460.7 28.1 Total 125 23061.2 Which predictor (if any) does not appear to be linearly correlated with blood pressure? Which reason supports your answer? ▸ All of the predictors are significant because thep-value from the global utility test is essentially zero. ▸ All of the predictors are significant because the R-Sq value is quite high (85%). ▸ Cholesterol does not appear to be linearly correlated with blood pressure because itsp- value is 0.937. ▸ Age does not appear to be linearly correlated with blood pressure because itsp-value is essentially zero.
