A random sample of 10 subjects have weights with a standard deviation of 11.0482 kg. What is the variance of their weights? Be sure to include the appropriate units with the result.

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

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

This implies that,

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
