8. The scatter plot below shows the relationship between height and shoulder girth (circumference of shoulders measured over deltoid muscles). 200 190 Height (cm) 160 170 180 O 150 90 100 110 120 130 Shoulder Girth (cm) The equation of the regression line for height vs shoulder girth is given by y = 0.6x + 106, where y refers to the height and a refers to shoulder girth. Which of the following statements is/are correct? Select all that apply. (1 mark) Using simple linear regression, when the height of the individual is 170cm, the predicted average shoulder girth is 106.67cm. If the shoulder girth of all the individuals above are 2cm shorter, then the gradient of the regression line for height vs shoulder girth is 0.6. Using simple linear regression, when the shoulder girth is equal to 141cm, the predicted average height is 190.6cm. O If we were to predict shoulder girth from height using simple linear regression, the gradient of the regression line is also positive
