The video states that 56% of high school students reported using sunscreen in 2011, while 68% reported using sunscreen in 2001, leading the researchers to conclude that sunscreen use is declining among this population. Describe a scenario in which this conclusion could be wrong.
(HINT: These percentages are estimates based on samples from this population. While you should assume that they calculated the estimates correctly, consider what other characteristics of these samples could lead to this conclusion being wrong.)
