Example: According to a 2017 survey, 80% of Americans used at least one type of social media regularly in 2017. Rodrigo wants to know if this percentage has decreased since then, so he collects some data. He randomly samples 200 people and finds that 154 of them still use at least one type of social media currently. Test the claim that less than 80% of Americans currently use at least one type of social media regularly. Use the 0.05 significance level.
