A 2016 study of 120 U.S. brand-name products found that 70% were active on Snapchat (businessinsider .com/what-exactly-are-brands-posting-on-snapchat -2016-6, June 15, 2016, retrieved May 4, 2017). The researchers conducting the study used bootstrap methods to determine a confidence interval. Suppose that it is reasonable to consider this sample of brand-name products as representative of all brand-name products. Use the “Bootstrap Confidence Interval for One Proportion” Shiny app to find a 95% confidence interval for the proportion of all brand-name products that are active on Snapchat and interpret the interval in context.
