Answer:
Step-by-step explanation:
Hello!
The null hypothesis is the commonly accepted fact, if you were to make an experiment, you'll state in the null hypothesis what is already known of your population, another way to see it is that the null hypothesis has the "no change" statement. When doing a statistic test you seek to nullify the null hypothesis to replace it with the alternative hypothesis, i.e., the objective of any hypothesis test is to invalidate this hypothesis not to prove the alternative hypothesis right.
In short words, you work to annulate what is accepted knowledge and not to prove what you think happens.
I hope it helps!
