Develop appropriate null and alternative hypotheses given a research question.

Alternative Hypothesis (H1): Receiving a flu vaccine reduces the risk of contracting the virus.
The null hypothesis suggests that there is no relationship between receiving a flu vaccine and being protected against the virus, while the alternative hypothesis posits that there is an association between these two variables. In order to test this hypothesis, researchers typically conduct experiments or observational studies involving individuals who have received one type of vaccination versus those who have not in order to compare their results. Through such analyses, it should be possible to determine if receiving a particular vaccination has any beneficial effects on reducing one’s susceptibility to catching influenza viruses. If found to be true, then it could provide further support for public health initiatives encouraging people to get vaccinated in order to lower their chances of getting sick from seasonal outbreaks.
