  • Draw a scatter plot
  • Fit a multiple regression equation.
  • Calculate the predicted average systolic blood pressure of a baby with birth weight 8 128 oz measured at 3 days of life.
  • Test the hypotheses that and at 5% level of significance.
  • Construct 95% C.I's for and and comment on regression.
  • Carry out an analysis of variance and test the significance of the regression using.
  • Compute the coefficient of multiple determinations and multiple correlation coefficients for the above example.
  • Carry out a residual analysis for the adequacy of the model estimated. Does any observation look like it could be influential? in its effect on the regression line?
  • If yes, identify the influential points and reanalyze, excluding the influential observation. What have you noticed?
