(Nursing) Here is how the process of statistical hypothesis testing works: We have two claims about what is going on in the population.Let's call them claim 1 (this will be the null claim or hypothesis) and claim 2 (this will be the alternative).Much like the story above, where the student's claim is challenged by the instructor's claim, the null claim 1 is challenged by the alternative claim 2. Additionally, statistical or research significance is estimated or determined by the investigators.
