To estimate proportions using bootstrapping methods, report successes as 1 and failures as 0. Then follow the sample procedures that we used to estimate a mean using bootstrapping. Suppose a random sample of 20 individuals was asked if the Internet is their main source of news. In the data, a 1 indicates the Internet is the main source of news and a 0 indicates the Internet is not the main source of news.
