An inter-strand grouping of students is working on a study about the Copper-infused materials utilization for real environment viruses and bacteria to address good health and well-being of the target beneficiaries. They want to compare the utilization and non-utilization of copper infused materials if it will yield the same results when introduced to reduce bacterial contamination. QUESTION: Will the choice of sampling technique affect the statistical test to be used? Also, what is the appropriate statistical test to use and why?
