- If your pail contains more than or equal to 30 and the variance is known or unknown, use the z-test.
- How about the Central Limit Theorem? It applies when the sample is ≥ 30 right?
- Wait, so if my pail has 30 or more shells, whether I know the variance or not, I still use the Z-test? That’s so much clearer

- Tumpak! But, if your pail contains less than 30 shells and you don't know the variance, then use t-test, okay?
- Thanks, Bella! You made stats feel less like a headache. I think I won't drop out anymore HAHAHA!
