This article shows how birth rates have decrease from January 2021-March 2022. The Data is based on 99.87% of March 2022 birth records received and processed by the National Center for Health Statistics. From this data, we see the birth rate was down from 2020.

My Ho hypotheses: I predict birth rates will continue to decrease as the years go by. My Ha hypothesis: I predict birth rates will not decline as the years go by. Based on my hypothesis I believe that it was a completed left tailed hypothesis. For a hypothesis to be done we need a null hypothesis, with a specific alternative and calculate the p value before drawing the conclusion.
