Think about how diet and weight-loss companies advertise. how do they use bias to sell their products? how would you use skepticism to evaluate the data that these companies use in their advertisements?

Diet and weightloss advertising puts super skinny models and actors/actresses saying they lost an insane amount of weight using their product. That is completely bias because they aren’t just going to say the model lost weight through other methods of weight loss because they are advertising THEIR product.
I would use skepticism evaluating these ads because I would be skeptical believing that someone lost 200 pounds in 2 months drinking some supplement.
