Answer: She should include a statistic to support her claim.
Step-by-step explanation:
A Bandwagon fallacy refers to claims that gets people to think that whatever is being claimed is being done by a significant number of people without the evidence to back it up. People will then think that they need to do whatever it is simply because so many people are doing it. For example, Everyone in class is going to watch the new Avengers movie this weekend.
These claims are often made without evidence but that does not mean that they are generally untrue. It is important to confirm such claims with actual statistics to support them which is what Estelle should do.
