5. Suppose a doctor telephones those patients who are in the highest 10% with regard to their recently recorded blood pressure and asks them to return for a clinical review. When she retakes their blood pressures, will those new blood pressures, as a group (that is, on average), tend to be higher than, lower than, or the same as the earlier blood pressures, and why? Choose the correct answer below. O A. The new blood pressures will tend to be the same. The high reading might be due to an underlying blood pressure condition, and regression toward the mean predicts that a repeated measurement will be close to the typical value. B. The new blood pressures will tend to be higher. The high readings put the data outside of the normal range of explanatory variables. Making predictions based on these values is extrapolation, which may result in predictions that increase in a nonlinear fashion. OC. The new blood pressures will tend to be higher. The high readings put the data outside of the normal range of explanatory variables. Making predictions based on these values is extrapolation, which may result in influential points which pull the readings upward. O D. The new blood pressures will tend to be lower. Part of the high reading might be due to chance, and regression toward the mean predicts that a repeated measurement will be closer to the typical value.
