Question

If 20 were added to each of the vlaues in a data set that originally had a standard deviation of 8, the standard deviation of the resulting data would be 28

Answer 1

False

Explanation:

Answer 2

False (I assume it's a true/false question)

Explanation:

Standard deviation measures how spread out the data is. If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before. The standard deviation does not change.
