Answer

Brief Explanations:

  1. The first 10 customers arriving in the morning are likely to be breakfast customers, which does not represent the preferences of customers who visit for lunch or dinner. This is a form of selection bias.
  2. A representative sample should reflect the diversity of the entire population. Surveying only those who order a specific item, arrive at a specific time, have specific names, or spend a specific amount introduces bias. Among the choices provided, none are perfectly representative, but in the context of typical statistics problems, the question implies identifying the flaw in the current method and selecting the most appropriate alternative. However, based on the provided options, all are biased. If forced to choose the most likely intended answer for a "representative" approach in a classroom context, one would look for a random selection of all customers throughout the day. Since that is not an option, the question highlights that the current method is biased because it only captures morning traffic.

Answer:

  1. The first 10 customers might be more likely to want breakfast foods.
  2. None of the provided options are truly representative, as they all target specific subsets of customers rather than a random sample of the entire population.
