Question

A random sample of 10 subjects have weights with a standard deviation of 13.5620 kg. What is the variance of their​ weights? Be sure to include the appropriate units with the result.

Answer 1

183.927844 kg²

Explanation:

Calculation for the weight variance:

Given that s =13.5620 kg

The Variance will be the square of the Standard Deviation

S²=13.5620 kg²

S²=183.927844

The units of the variance will be the units of the Standard Deviation Squared which is Kg²

Therefore the variance of their weight will be:

183.927844 kg²
