Question

which statement is true of an appropriate sample of a population? a sample must be a group of people who are the target of the survey question. a sample should have different characteristics than the population. a sample must be very small. a sample should include only boys or only girls.

Explanation:

• For the first option: A sample in a survey should be representative of the population, so it must consist of the target group of the survey question. This aligns with sampling principles.
• For the second option: A sample should have similar characteristics to the population to be representative, not different.
• For the third option: A sample doesn't have to be very small; it just needs to be representative (can be small or large depending on the population and study).
• For the fourth option: A sample including only boys or only girls would be biased and not representative of a population that likely has both genders.

Answer:

A. A sample must be a group of people who are the target of the survey question.
