question 165

Short Answer

Which of the following best describes the y-intercept in the simple linear regression model? $\begin{array}{|l|l|}\hline\text { A. } & \text {The \( \mathrm{y} \)-intercept is the estimated average value of \( \mathrm{y} \) when \( \mathrm{x}=1 \). }\\\hline \text { B. } & \text { The \( \mathrm{y} \)-intercept is the estimated average value of \( \mathrm{x} \) when \( \mathrm{y}=0 \).} \\\hline \text { C. } &\text {The \( \mathrm{y} \)-intercept is the rate of change of \( \mathrm{y} \) with respect to changes in \( \mathrm{x} \). }\\\hline \text { D. } &\text { The \( \mathrm{y} \)-intercept is the estimated average value of \( \mathrm{y} \) when \( \mathrm{x}=0 \).}\\\hline\end{array}$
