Case study; There is no real debate over vaccines. Essentially all medical doctors, scientists, research technicians, healthcare administrators, and politicians agree that vaccines are safe, effective, and lifesaving. This huge consensus among educated professionals was reached because of the large body of evidence demonstrating the efficacy and safety of vaccines. The small but vocal minority that argues against the use of vaccines consists of non-scientific "alternative" healthcare peddlers and their gullible victims. A legitimate debate in educated circles requires evidence on both sides of the debate. Seeing as there is no evidence that vaccines fail or do significant harm, there is no real debate. Let us see what a legitimate scientific debate looks like and how it is resolved, and then look at some numbers.

Base on the case study;

1. Identify the dependent and independent variable

2. Which form of non/semi parametric test can be applied to provide conclusion and significance for the results

3. What is the best null and alternative hypothesis for the study?

4. How do we normally make conclusion and based on decision criteria of t statistic values
