Answer:

Variance is 123.14 square kilograms.

Step-by-step explanation:

We have been given that

[tex]N=10,\sigma=11.0974\text{ kg}[/tex]

Now, we know the formula,

[tex]\tex{Variance}=\sigma^2\\\\\tex{Variance}=(11.0974)^2\\\\\tex{Variance}=123.15\text{ kg}^2[/tex]

Hence, the variance is 123.14 square kilograms.
