Question 5: CLO-4 (8 pts) (Linear Regression) A seoncd hand car dealear has 10 cars for sales. He decides to investigate the link between the age of the cars, x years, and the mileage, y thousand miles. The data collected from the cards are showing the the table below. 4 4.5 5 2 3 4.5 3 6 2.5 6.5 Age, x (years) Mileage, y (thousands) 33 37 22 34 40 45 49 30 58 58 a) Find the equation of regression line of y on x in the form of y = a + bx. b) Draw a scatter diagram to represent these data, c) Draw the best fit regression line using the regression equation d) Calculate the errros squared value i.e., (y - 9) y = a+bx b= 2(x-3)(y-4) (x-x) a = y - bx
