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

Answer:

$123.19890025 kg^2$

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=$(standard\;deviation)^2$

Using the formula

The variance of their​ weights

=$(11.0995)^2$

=$123.19890025 kg^2$

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