![### Problem Statement
A random sample of 10 subjects have weights with a standard deviation of 13.0505 kg. What is the variance of their weights? Be sure to include the appropriate units with the result.
### Instructions
The variance of the sample data is:
(Use a dropdown to select the unit of measurement)
(Round to four decimal places as needed.)
---
**Explanation:**
To find the variance given the standard deviation, you can use the following formula:
\[ \text{Variance} = (\text{Standard Deviation})^2 \]
Given:
- Standard Deviation = 13.0505 kg
Substitute the value into the formula:
\[ \text{Variance} = (13.0505)^2 \]
Calculate the variance and round the final result to four decimal places, including the appropriate unit of measurement (kg²).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6a767b23-c124-4e33-a8c8-1cb736a4d72e%2Fb1561831-bd57-422b-9081-82a5870ebc9e%2Fzq4ih0f_processed.jpeg&w=3840&q=75)
