which sample fairly represents the population? select two options. using a yearbook to determine the most popular names for girls in the united states asking the people exiting a vitamin store how often they exercise to determine the amount of time the average american exercises calling every registered member of the national republican party to determine the voter turnout for a citys mayoral race sending a mandatory and confidential e - mail survey to every tenth employee of a company to determine overall job satisfaction taking a poll in the main hallway between classes to determine the number of students who would be interested in a school trip to new york city
Answer
# Brief Explanations:
1. Using a year - book to determine popular girl names in the US may not be representative as year - books may not cover all regions or demographics evenly.
2. Asking people exiting a vitamin store about exercise is a biased sample since they are likely more health - conscious than the general American population.
3. Calling only Republican Party members to determine mayoral voter turnout is biased as it only represents one political party and not the entire city's population.
4. Sending a survey to every tenth employee of a company can be a systematic random sample and may fairly represent the company's employees' job satisfaction if the company's structure doesn't introduce hidden biases.
5. Taking a poll in the main hallway between classes can be a convenience sample, but if the hallway is a central location where a diverse group of students pass by, it can fairly represent student interest in a school trip.
