Final answer:

To achieve a representative sample of airline customers, the best method is for airline representatives to make phone calls to a random selection of customers.


Explanation:

The most representative sample of the population of airline customers would be achieved by method:

  1. A. Airline representatives make phone calls to a random selection of customers. This method ensures randomness in selecting customers, giving each customer an equal chance of being surveyed, thus making the sample representative of the entire population.

Other methods like

  1. B. Airline representatives survey all customers who flew first class in a given week
  2. C. Airline representatives survey all customers who flew from Dallas to Chicago
  3. D. Airline representatives survey all passengers as they arrived at their destination on a randomly selected day

may introduce bias by focusing on specific subsets of customers rather than a random selection.
