1. What is the hypothesis that will be tested in the experiment?

If the model added milk before the coffee, then she would be able to taste the difference if she added the milk after the coffee.

It is important to offer the model more than just two cups because the more the better. The more cups you have, the data would be more accurate and reproducible.

I recommend that the model should get nine out of ten cups correct, stating whether milk was added before the coffee or added after the coffee. I think that nine out of ten is the best choice because we need to have at least 90% accuracy.

7. Without looking it up in a textbook or online, provide your own definition of "experimental design".

Experimental Design is when you take time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.
