Answer:

The variance is 122.0627 kg

Step-by-step explanation:

The square of the standard deviation of a distribution gives us the variance.

If a random sample of 10 subjects have weights with a standard deviation of 11.0482 kg.

Then the standard deviation is

[tex] { \sigma} = 11.0482[/tex]

To get the variance, we square both sides to get;

[tex]{ \sigma}^{2} = 11.0482^{2} [/tex]

This implies that,

[tex]{ \sigma}^{2} = 122.0627kg[/tex]
