Question

Which of these random samples qualifies as a representative sample to find out what parents think about the levels of college tuition fees in the state? a.) 50 residents of a city in the state b.) 50 parents of college students from another state c.) 50 parents of college students from the state d.) 50 residents of a county in the state

Answer 1

The correct answer is C) 50 parents of college students from the state

Explanation:

The purpose of representative samples is to study a population by only selecting a small group in it. Due to this, the individuals selected as part of the sample need to match the characteristics of the population being studied.

In this context, if the focus is the opinion of parents about college tuition fees in a specific state, it is expected the sample includes parents of college students rather than students, citizens, etc. because the opinion of parents of college students is being evaluated. Moreover, those parents selected should have children in the state being studied. According to this, the correct option is C because this includes individuals who can appropriately represent the population that is being analyzed.
