This is a binomial experiment because we have

  1. Fixed number of trials - 1616 Americans in the sample
  2. Two possible outcomes - a person has (success) or does not have (failure) high blood pressure
  3. A person's blood pressure does not affect another's
  4. The probability of success remains the same (20%20\%)
