Stating the null and alternative hypotheses correctly is crucial to using data to answer research questions. Stating it in words and using statistical notation is also vital to make sure everyone is clear on what needs to be tested in order to answer the research question.

For your initial post state in words the null and alternative hypotheses for your chosen health question. Then present both hypotheses again using statistical notation. Next, discuss if there is another way that you can word your hypotheses and maintain the same meaning as your original wording, and present this alternative wording.
