Question:medium

If standard deviation of the data \[ 1,15,35,53,72,64 \] is \(x\), then the variance of the data \[ 62,70,51,33,13,-1 \] is

Show Hint

Adding or subtracting a constant from all observations does not change variance. Also remember that variance is the square of the standard deviation.
