There appears to be a negative : linear relationship between x and y. c. Try to approximate the relationship between x and y by drawing a straight line through the data. Only one straight line can be drawn * to provide a linear approximation of the relationship between x and y. d. Develop the estimated regression equation by computing the values of bo and bị using equations: (Enter negative values as negative figure) - 7)(yi – 9) b1 = (x; – 7)? bo = y – bị a 77.68 + 2.96 x (to 2 decimals) e. Use the estimated regression equation to predict the value of y when x = 6. ü = 95.44 (to 2 decimals)
