Question 5 Twelve pairs of values of x and y, where x is the independent variable with values between -15.8 and 18.0, yield the following results: [x = 0, Σxy=-246.38, [x² = 1054.56 a. Given that the regression line y on x has equation y = 35.4 + bx, calculate the values of b and y. b. The product moment correlation coefficient between x and y is -0.0938, correct to 3 significant figures. Justifying your answer, state whether an estimate for y obtained using the line y on x and a value of x = 3.4 is reliable.
