Statistics QUESTION #1998

Question 1418

In a simple linear regression of number of breakdowns $(Y)$ on machine age $(X)$, the least squares estimate of slope $\hat{\beta}$ is given by:

$\dfrac{SS_{xy}}{SS_{xx}}$✔️
$\dfrac{SS_{xx}}{SS_{xy}}$
$\dfrac{SS_{yy}}{SS_{xx}}$
$\dfrac{SS_{xy}}{SS_{yy}}$

Correct Answer Logic:

The least squares slope estimate is $\hat{\beta} = \dfrac{SS_{xy}}{SS_{xx}} = \dfrac{\sum(X_i - \bar{X})(Y_i - \bar{Y})}{\sum(X_i - \bar{X})^2}$. The intercept is then $\hat{\alpha} = \bar{Y} - \hat{\beta}\bar{X}$.
