Question 647783: Following are many patients' diastolic blood pressure (mm Hg) figures. The standard deviation is about 6. If you were to add 5 to all of them, what would be the new standard deviation?
80, 91, 81, 75, 72, 76, 84, 90, 95, 77, 79, 86, 71, 75, 89, 85, 80, 77, 74, 80, 79, 82, 90, 83, 81, 72, 82, 78, 80

You can put this solution on YOUR website! The spread will still be the same, although each number would be 5 higher.
So the standard deviation would still be 6.
