A shoe manufacturer that exclusively makes leather shoes finds a study that shows 3 out of 10 people buy nylon shoes. The study was funded by a nylon producing company. What is the problem with this study?

The problem with this study is the potential conflict of interest introduced by the fact that it was funded by a nylon producing company. This creates a bias towards promoting nylon shoes and may influence the results and conclusions of the study in favor of nylon shoes. The study may not be impartial and objective, as the funding source could have influenced the study design, methodology, and interpretation of the data to promote their own product. Therefore, the study's findings may not accurately represent the preferences or behaviors of consumers when it comes to choosing between leather and nylon shoes.
