question 6

Multiple Choice

An automotive engineer computed a least-squares regression line for predicting the gas mileage (mile per gallon) of a certain vehicle from its speed in mph. The results are presented in the following Excel output.
$\begin{array}{l|c} & \text { Coefficients } \\\hline \text { Intercept } & 32.4881657 \\\hline \text { Speed } & -0.10266272\end{array}$
Write the equation of the least-squares regression line.

• A) \(y = - 0.10266272 + 32.4881657 x\)
• B) \(y = 32.4881657 + 0.10266272 x\)
• C) \(y = - 32.488166 + 0.10266272 x\)
• D) \(y = 32.4881657 - 0.10266272 x\)
