Question

If the variance is 28 kg2 what is the standard deviation?

Answer 1

The standard deviation is 5.29 kg.

Explanation:

The standard deviation is the square root of the variance. Mathematically, we have that:

`S(X) = √(V(X))`

In this problem, we have that:

`V(X) = 28`

So

`S(X) = √(V(X))`

`S(X) = √(28)`

`S(X) = 5.29`

The standard deviation is 5.29 kg.
