SAMPLE REGRESSION EQUATION OF : X ON YIS Select one: M(Xvert _(y))=f(y) bar (x)_(y)=varphi ^ast (y) overline (y_(x))=f^ast (y) M(Yvert _(x))=f(x) overline (y_(x))=f^ast (x)

The correct answer is: $\bar {x}_{y}=\varphi ^{\ast }(y)$<br /><br />Explanation: The sample regression equation of X on Y is represented by the equation $\bar {x}_{y}=\varphi ^{\ast }(y)$, where $\bar {x}_{y}$ is the expected value of X given Y, and $\varphi ^{\ast }(y)$ is the regression function of X on Y.
