The Data Below Are Ages and Systolic Blood Pressures (Measured

question 39

Multiple Choice

The data below are ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomlyselected adults. Find the equation of the regression line for the given data. What would be the predictedpressure if the age was 60? Round the predicted pressure to the nearest whole number. Round the regressionline values to the nearest hundredth. $\begin{array}{l|c|c|c|c|c|c|c|c|c|}\text { Age, } \mathrm{x} & 38 & 41 & 45 & 48 & 51 & 53 & 57 & 61 & 65 \\\hline \text { Pressure, } \mathrm{y} & 116 & 120 & 123 & 131 & 142 & 145 & 148 & 150 & 152\end{array}$

• A) \(\hat { y } = 1.49 x + 60.46 ; 150 \mathrm {~mm}\)
• B) \(\hat { y } = 60.46 \mathrm { x } - 1.49 ; 3626 \mathrm {~mm}\)
• C) \(\hat { y } = 1.49 \mathrm { x } - 60.46 ; 29 \mathrm {~mm}\)
• D) \(\hat{ y } = 60.46 \mathrm { x } + 1.49 ; 3629 \mathrm {~mm}\)
