The equation yˆ=1.2676x+79.6645 models Fred’s systolic blood pressure, in mm/HG , over his life span, where x is Fred’s age. According to the regression equation, what is the approximate systolic blood pressure of Fred at the age of 55?
The equation that models Fred`s systolic blood pressure is: y = 1.2676 * x + 79.6645 x = 55 ( the age of 55 ) y = 1.2676 * 55 + 79.6645 = = 69.718 + 79.6645 = = 149.3825 Answer: The approximate systolic blood pressure of Fred at the age of 55 is 149.3825 mm/HG.
