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.

(a) What is the sample proportion of individuals who use the Internet as their main source of news?

(b) Explain why the normal model cannot be used to construct a confidence interval about the population proportion.

(c) Construct a 95% confidence interval for the proportion of individuals who use the Internet as their main source of news.
