Be sure to check the options at the bottom of the linear regression dialog box.


a. Determine the correlation coefficient between weight (X3, the independent variable) and systolic pressure (X2, the dependent variable). Describe your findings related to the magnitude and sign of the correlation. 
b. Determine the regression equation between weight and systolic pressure using the coefficients in the output. Interpret the meaning of each coefficient.
c. Discuss the statistical meaning of the residuals shown in the Residual Output table.
d. Evaluate the residual plot, and discuss your interpretation.
e. Would you suspect that any of the data points might be considered outliers? On what do you base your decision?
