question 106

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.
