In a survey of 2200 randomly selected US adults (age 18 or older), 1876 of them use the Internet regularly. The survey shows that on an average day 35% use Facebook, 30% use Instagram, 22% use Twitter. For each of the bulleted social networks, find a 95% confidence interval for the proportion of Internet users spending time on that social network on an average day. Is it plausible that the proportion of Facebook users is the same as the proportion.
