Which of the Following Statements Are True?
A) the True $y = \beta _ { 0 } + \beta _ { 1 } x$

Multiple Choice

Which of the following statements are true?

A) The true regression line $y = \beta _ { 0 } + \beta _ { 1 } x$
Is the line of mean values.
B) The height of the true regression line $y = \beta _ { 0 } + \beta _ { 1 } x$
Above any particular x value is the expected value of Y for that value of x.
C) The slope $\beta _ { 1 }$
Of the true regression line $y = \beta _ { 0 } + \beta _ { 1 } x$
Is interpreted as the expected change in Y associated with a 1-unit increase in the value of x.
D) The equation
States that the amount of variability in the distribution of Y values is the same at each different value of x (homogeneity of variance) .
E) All of the above statements are true.
