Healthcare related Hypothesis test study

I’m studying for my Statistics class and don’t understand how to answer this. Can you help me study?

 

Describe a hypothesis test study that would help your work or conclusions in some way. Describe what variable would be tested and what would be your guess of the value of that variable. Then include how the result, if the null were rejected or not, might change your conclusions or actions in some way.

Please use 2 APA references.

Minimum of 3 paragraphs please

MUST use a healthcare related Hypothesis test study, something related to cardiovascular health.

Please message me with questions!

Thanks!
