To find the variance, you use the formula:

$\text{Variance} = (\text{Standard Deviation})^2$

Given:

• Standard Deviation = 12.2207 kg

So, the variance will be:

$\text{Variance} = (12.2207 \, \text{kg})^2$

Now, let's calculate it.The variance of the weights is $149.3455 \, \text{kg}^2$.

Would you like more details or have any other questions?

Here are 5 related questions you might find interesting:

1. What is the difference between standard deviation and variance?
2. How would you interpret a high variance versus a low variance in a dataset?
3. What is the formula for the variance of a population as opposed to a sample?
4. How would the variance change if we doubled the standard deviation?
5. Can you explain why variance has squared units compared to standard deviation?

Tip: Remember that variance is always in squared units of the original data, which often makes it less intuitive than the standard deviation when interpreting data.
