Question

A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their​ weights?

Answer 1

`123.19890025 kg^2`

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=
`(standard\;deviation)^2`

Using the formula

The variance of their​ weights

=
`(11.0995)^2`

=
`123.19890025 kg^2`

Hence, the variance of their​ weights=
`123.19890025 kg^2`
