The table below lists the blood pressure (mm Hg) in both arms of 5 patients.

Right Arm	102	101	94	79	79
Left Arm	175	169	182	146	144

a) Construct a scatterplot for the bivariate data. Label all details

b) Let the blood pressure in right arm be x, and the blood pressure in left arm be y. Use the TI calculator to obtainx , s_x , y, s_y . Then compute the correlation coefficient r . Show all steps.

c) Compute the least-squares regression line for the blood pressures in both arms. Show all steps.

d) Use the least-squares regression line obtained in part c to predict the blood pressure in the left arm of a patient with blood pressure in right arm that is 100 mm Hg.
