Answer: 16
Step-by-step explanation:
We know that the standard deviation is the square root of the variance of a data.
Given : The variance of the data values in population is [tex]\sigma^2=256[/tex].
Then, the standard deviation will be :_
[tex]\sigma=\sqrt{256}=\sqrt{16^2}=16[/tex]
Therefore, the standard deviation of the data values= 16.
