Question 1

Consider the model where x1 is a quantitative variable and x2 and x3 are dummy variables describing a qualitative variable at three levels using the coding scheme


The resulting least squares prediction equation is What is the response line (equation) for E(y) when and
◦ = 18.1 + 2.3x1
◦ = 16.3 + 4.1x1
◦ = 16.3 + 2.3x1
◦ = 18.6 + 2.3x1

Question 2

Consider the model where x1 is a quantitative variable and x2 and x3 are dummy variables describing a qualitative variable at three levels using the coding scheme


The resulting least squares prediction equation is What is the least squares regression equation associated with level 2?
◦ = 38.0 + 5.4x2
◦ = 39.9 + 1.3x1
◦ = 39.9 + 5.4x2
◦ = 42.1 + 1.3x1
