Suppose you measure the blood pressure of 100 hypertensive people and find that they have a mean systolic blood pressure of 133 mm Hg with a variance of 9 mm Hg. You later discover that your blood pressure monitor was calibrated incorrectly. To adjust for this mistake, you add 5 mm Hg to each person's systolic blood pressure. What is the standard deviation of the new data shifted by 5 mmHg?
