Binomial Distribution
1. State a question that can be answered in a "binomial" manner, such as Do you normally read the front page of a newspaper at least 4 times a week? (yes or no).
Determine ahead of time whether answers should be recorded or counted as a "yes " or "no".
2. Take a survey. Ask 22 individuals to respo
