Rayna studied rats in a lab. She observed that all 50 rats in her sample preferred to eat brand A rat food and would eat brand B food only when brand A was not available. Can she correctly conclude that all rats prefer brand A rat food over brand B food? Why or why not?

the standard deviation is zero

Explanation:

In the experiment performed when both meals are available, rats prefer food A and eat only B when no other is available.
