Question

which sample fairly represents the population? select two options. using a yearbook to determine the most popular names for girls in the united states using 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

Explanation:

• Option 1: A yearbook likely doesn't cover all girls in the US, so it's not a representative sample.
• Option 2: People exiting a vitamin store are more likely to be health - conscious and exercise more, so it's a biased sample.
• Option 3: Surveying only Republican Party members doesn't represent all voters in a city's mayoral race.
• Option 4: Sending a survey to every tenth employee is a form of systematic sampling which can be representative.
• Option 5: Taking a poll in the main hallway between classes can reach a diverse group of students (assuming it's a large enough sample) and can be representative.

Answer:

D. Sending a mandatory and confidential e - mail survey to every tenth employee of a company to determine overall job satisfaction; E. 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.
