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.
1 answer:
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
