Hypothesis testing: Should I write the null hypothesis H0 as what have been claimed or write the alternative hypothesis H1 as what being observed in the reality?

Question

I have some problem with my exercise, it wants me to conduct a hypothesis test. I found that what occurs in the reality (from the given data) satisfies the claim of a research, but if it's already satisfied then how could I conduct a hypothesis test, I mean the test can only be applied when the reality is different/opposite with the claim. My teacher said that it's better to start with H1 as what you observe in the reality then go back with the H0 as the opposite, but if I do so, the H0 will be opposite towhat have been claim in my exercise.

Please help me because I have an exam next week!

Answer 1

the H0 null hypothesis states the opposite of what the researcher predicts.It defines the statement which states that there is no exact or actual relationship between the variables.

the alternative or H1 hypothesis suggests or advises a potential result or an outcome that a researcher may expect.
