Question

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

Answer 1

Answer:

The standard deviation is 5.29 kg.

Step-by-step explanation:

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

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

In this problem, we have that:

$V(X) = 28$

So

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

$S(X) = \sqrt{28}$

$S(X) = 5.29$

The standard deviation is 5.29 kg.
