Many different straight lines can be drawn to provide a linear approximation of the relationship between x and y ; in part (d) we will determine the equation of a straight line that “best” represents the relationship according to the least squares criterion. d. 325 585 65 117 5 5 i i x y x y n n Σ Σ = = = = = = 2 ( )( ) 110 ( ) 20 i i i x x y y x x Σ = Σ = 1 2 ( )( ) 110 5.5 20 ( ) i i i x x y y b x x Σ = = = Σ b y b x 0 1 117 5 65 2405 = = = (5. )( ) . . . y x = + 2405 55 e. . . . .
