The Data Below Are Ages and Systolic Blood Pressures (Measured

Multiple Choice

The data below are ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomly selected adults. Find the equation of the regression line for the given data. $$\begin{array} { l | c | c | c | c | c | c | c | c | c | } \text { Age, } \mathrm { x } & 38 & 41 & 45 & 48 & 51 & 53 & 57 & 61 & 65 \\\hline \text { Pressure, } \mathrm { y } & 116 & 120 & 123 & 131 & 142 & 145 & 148 & 150 & 152\end{array}$$

A) $\hat { y }$ = 1.488x + 60.461
B) $\hat { y }$ = 60.461x - 1.488
C) $\hat { y }$ = 1.448x - 60.461
D) $\hat { \mathrm { y } }$ = 60.461x + 1.488
