1. Five percent of American truck drivers are women. Suppose 10 truck drivers are selected randomly to be interviewed about quality of work conditions.

A. Is the selection of the 10 drivers a binomial experiment? Explain the reasons for your answer.

Answer
The binomial distribution arises from the following assumptions:
1. There are n trials.
2. Each trial has two possible outcomes, "success" or "failure".
3. The probability of success, p, is the same for each trial.
4. Each trial ...
