How do I formulate a hypothesis for an engineering project?

Question by Gulienne Pierre: How do I formulate a hypothesis for an engineering project?

I am building a device that could treat a certain disease….so how do I formulate a hypothesis?
Also, I’m not really sure how to collect numerical data, because it is a device …I need help lol sorry I am in high school. And how do I keep on journal for my project? What should I write inside of it??

I’m sorry if these questions may seem stupid, but this is my first engineering project and I have no guidance.

This is all rather vague.
Your journal should directly record everything you do related to the project.
If you want numerical data, you must devise some measurement that will produce numbers. There should be two at least: some measure of the application of your device, and some measure of the results.
The routine hypothesis to test is whether or not your process had an effect, hopefully beneficial. For this, you will need to be able to compare one bunch with treatment, and another bunch without the treatment, and look to see if there is a significant difference between the two groups.
