Compose a written report based on research from Covid-19 vaccination in the United States and effectiveness statistics. You will choose two articles on the topic and review the findings and statistical analyses found in the papers. Read each paper in its entirety, but your focus for this paper should be on the statistical analyses done in each study.

Structure example as follows:

1. Introduce the topic and problem.
2. Summarize the studies and findings for each of the papers you reviewed.
3. Identify and explain the statistical tests done in each study. (Refer to course content -- videos, readings, and textbook chapters -- to help you identify statistical approaches).
4. Compare and contrast the statistical analysis done in each study. Identify similarities and differences. Explain why you think the approaches varied.

• Include at least two high-quality, peer-reviewed studies.
