I'm confused about hypothesis parameters. sometimes they use mu which represents for mean, and sometimes they use trou which represents
for treatment effect , but how do I know which one should I use? it depends on what?
I have attached a file(right down below) that gives an example and the solution.
for the first problem they use mu, but the second one they use trou, why is that?
