Question

If the standard deviation is 8.6kg. What is the variance?

Answer 1

Answer : The variance is, $73.96kg^2$

Step-by-step explanation :

As we know that the standard deviation is the square root of the Variance.

Formula used :

$\text{Standard deviation}=\sqrt{\text{Variance}}$

Given:

Standard deviation = 8.6 kg

Now put the value of standard deviation in above formula, we get:

$8.6kg=\sqrt{\text{Variance}}$

$\text{Variance}=(8.6kg)^2$

$\text{Variance}=73.96kg^2$

Therefore, the variance is, $73.96kg^2$

Answer 2

Answer:

Variance = 73.96 $Kg^{2}$

Step-by-step explanation:

We are given that standard deviation is 8.6 kg.

Now, Variance formula = $Standard deviation^{2}$

                                    = $8.6^{2}$ = 73.96 $Kg^{2}$.
