Answer
# Brief Explanations:
1. A year - book is likely to be from a single school or a limited set of schools and not represent all girls in the US for popular names.
2. People exiting a vitamin store are more likely to be health - conscious and not represent the average American's exercise habits.
3. Calling only Republican Party members won't represent all voters for a city mayoral race.
4. Sending a survey to every tenth employee can be a systematic random sample and can fairly represent the overall job satisfaction of employees in a company.
5. Polling students in the main hallway between classes can be a convenient sample of students in the school and can represent the interest in a school trip among students.
