Suppose That the Regression Equation Y = 16

Multiple Choice

Suppose that the regression equation y = 16.99 + 0.32 x₁ + 0.41 x₂ + 5.31 x₃ predicts an adult's height (y) given the individual's mother's height (x₁) ,his or her father's height (x₂) ,and whether the individual is male (x₃ = 1) or female (x₃ = 0) .All heights are measured in inches.In this equation,the coefficient of ______ means that ______.

A) x₂; if two individuals have fathers whose heights differ by 1 inch, then the individuals' heights will differ by 0.41 inches.
B) x₂; if two individuals have mothers whose heights differ by 1 inch, then the individuals' heights will differ by 0.41 inches.
C) x₃; a brother is expected to be 5.31 inches taller than his sister
D) x₁; if two individuals have mothers whose heights differ by 0.32 inch, then the individuals' heights will differ by 1 inch.
E) x₁; if two individuals have mothers whose heights differ by 0.5 inch, then the individuals' heights will differ by 0.32 inch.
