A patient is injected with the drug and the concentration (units/cc) in the patient's blood is measured every hour for seven hours. Based on the linear regression output
Below, which of the following is true?
Regression Analysis:
The regression equation is
Concentration = 41.3 - 6.00 Time Elapsed
S = 4.72077 R-Sq = 90.0%
Concentration versus Time Elapsed
A) The linear model is appropriate given that it explains 90% of the variability in Blood concentration levels of the drug.
B) If the observed pattern continues into the future, this model will underestimate the Concentration level after 10 hours has elapsed because the linear model is not Appropriate.
C) If the observed pattern continues into the future, this model will overestimate the Concentration level after 10 hours has elapsed because the linear model is not Appropriate.
D) Both A and B.
E) Both A and C.
