Medical Researchers Conducted a Study Designed to Evaluate the Relationship

Multiple Choice

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: ​

Which predictor (if any) does not appear to be linearly correlated with blood pressure? Which reason supports your answer?

A) All of the predictors are significant because the p-value from the global utility test is essentially zero.
B) All of the predictors are significant because the R-Sq value is quite high (85%) .
C) Cholesterol does not appear to be linearly correlated with blood pressure because its p- value is 0.937.
D) Age does not appear to be linearly correlated with blood pressure because its p-value is essentially zero.
