If the standard deviation is 7.3kg, what is the variance?

sasho [114]

Answer:

The variance is 53.29 kg²

Step-by-step explanation:

The standard deviation is the square root of the variance.

So

$S(X) = \sqrt{V(X)}$

In which problem, we have that:

$S(X) = 7.3$

So

$\sqrt{V(X)} = 7.3$

$\sqrt{V(X)}^{2} = (7.3)^{2}$

$V(X) = 53.29$

The variance is 53.29 kg²
