A description of what alpha and beta represent in a hypothesis test.

The word you were looking for is "acquitting" (letting a guilty man go free)

You sir have explained this so well....you are better than 2 of my professors, and probably 10 other people that I have seen videos for them explaining this on youtube.. a small hint.. I have been trying to get a deep understanding of this because I'm interested in quality control and stuff like that.. and you helped me a lot.. hats off to your effort.. I can't reward you with anything except by praying for you every time I remember you :)
Seriously.. thank you.

If you use the term "Null Hypothesis", there is often a failure to state the "Research Hypothesis" - in very clear format. In a scientific study, there is often a failure to spell this concept out completely.

One thing that bothers me in math classes is when they put up a symbol and don't explain what it's for. What is "a"? I'm assuming it's not the same as alpha... bc that would be saying that the null hypothesis would be the average of the entire population equals the probability of making a type I error. Which makes absolutely no sense.

is the word you are looking for false positive and false negative?

acquitting someone does't imply they were actually guilty. Being acquitted of your crimes simply means you were found innocent of the charges brought against you.
