Question

A random sample of 10 subjects have weights with a standard deviation of 11.0974 kg. What is the variance of their​ weights? Be sure to include the appropriate units with the result.

Answer 1

Answer:

Variance is 123.14 square kilograms.

Step-by-step explanation:

We have been given that

$N=10,\sigma=11.0974\text{ kg}$

Now, we know the formula,

$\tex{Variance}=\sigma^2\\\\\tex{Variance}=(11.0974)^2\\\\\tex{Variance}=123.15\text{ kg}^2$

Hence, the variance is 123.14 square kilograms.
