Data Point ... 1 6 4 2 1 9 3 4 6 4 3 7 5 8 3 6 5 5 7 1 8 9 7 2 3 7 Use Linear Regression (LR) method to develop a model that predicts the value of (y) in terms of(x). (a) Write down the model. i.e. the line equation y=-0.9x+9.5 ((Important don't leave any space between the components of the line equation, e.g: y=-4.3x+2.8)) (b) The slope of this model is: -0.9 (c) The line intersects the y-axis at y = 9.5 (d) Use the model you developed in (a) to predict the value of y when x = 4. Blank 4 (e) When x = 11, what is the type of LR. is it interpolation or extrapolation?: Blank 5 ((Important: Mind your spelling)) (f) The MAE for the model you developed from the above data = Blank 6
