Explanation:

Brief Explanations
  • Population: A population is the entire group of individuals or items that we are interested in studying. In this case, "the number of computers in all households in the city" represents the entire set of households in the city, which is the population.
  • Sample: A sample is a subset of the population. "The number of computers in one household in the city" is a single element from the population (a very small subset). "The number of computers in every other household on a street in the city" is a subset of households on a particular street. "The number of computers in all households of a neighborhood in the city" is a subset of the city's households (a neighborhood is part of the city).

Answer:

  • Populations: C. the number of computers in all households in the city
  • Samples: A. the number of computers in one household in the city, B. the number of computers in every other household on a street in the city, D. the number of computers in all households of a neighborhood in the city
