To estimate proportions using bootstrapping methods, report successes as 1 and failures as 0. Then follow the same procedures that we used to estimate a mean using bootstrapping. Suppose a random sample of 25 50- to 64-year-old Americans were asked if they feel younger than their actual age. In the data, a 1 indicates the individual feels younger and a 0 indicates the individual does not feel younger.
