Question

A random sample of 10 subjects have weights with a standard deviation of 11.0482 kg. What is the variance of their weights? Be sure to include the appropriate units with the result.

## Answers ( )

Answer:122.0627kg

Step-by-step explanation:The standard deviation is the square root of the variance.

That means:

From the question, the standard deviation of the weights of the 10 random subjects is 11.0482kg

We substitute to get:

We square both sides to get:

Therefore the variance is 122.0627kg
