Answer:

[tex]123.19890025 kg^2[/tex]

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance=[tex](standard\;deviation)^2[/tex]

Using the formula

The variance of their​ weights

=[tex](11.0995)^2[/tex]

=[tex]123.19890025 kg^2[/tex]

Hence, the variance of their​ weights=[tex]123.19890025 kg^2[/tex]
