Answer: The answer is 361.
Step-by-step explanation: We are given that the standard deviation of a data is 19 and we are to find the variance of the data values.
we know that the variance of a data is the square f the standard deviation of the data values, so if the standard deviation is given to be 19, then the variance will be
[tex]V=19^2=361.[/tex]
Therefore, the variance of the data values will be 361.
Thus, the answer is 361.
