Solution Steps

The question asks us to identify which of the given samples is a representative sample to determine what parents think about college tuition fees in the state. A representative sample should accurately reflect the population of interest, which in this case is parents of college students in the state.

• Option a: 50 parents of college students from another state.
  This sample is not representative because it includes parents from another state, who may have different opinions and experiences regarding college tuition fees.

• Option b: 50 residents of a county in the state.
  This sample includes residents, not specifically parents of college students, so it may not accurately reflect the opinions of the target population.

• Option c: 50 parents of college students from the state.
  This sample is representative because it specifically targets parents of college students within the state, aligning with the population of interest.

• Option d: 50 residents of a city in the state.
  Similar to option b, this sample includes residents, not specifically parents of college students, and may not accurately reflect the target population's opinions.

Based on the analysis, option c is the most representative sample because it directly targets the population of interest: parents of college students in the state.
