[6 marks] The following graph shows the regression model "Birth-Weight = 21.6 + 0.596*Oestriol Level" where the data points A and B were excluded from the analysis. If you rerun the regression with all data points including A and B, what would be the possible effects of these two new data points (A and B) on the constant (baseline effect) and beta coefficient of the regression model?
