A production possibilities frontier (PPF) is a function that shows the different combinations of two goods that can be produced by a country, firm, or any other economic agent, given a fixed initial endownment of factors of production that is totally consumed. Therefore, the points in the function take the following form: (x ,y)= (quantity produced of good x, quantity produced of good y).
The PPF function also represents two crucial economic concepts: efficiency and opportunity cost. The opportunity cost is defined as the value of the best alternative rejected when making a decision. When moving along the PPF line, if a combination is chosen so that a extra unit of good x is produced, some units of good y need to be given up (due to the fixed amount of inputs available). Those given up units would constitute the opportunity cost.
<u>Combinations of x and y located along the curve are efficient because they represent output quantities obtained by using the whole factor endowment available.</u> Points located below the curve are considered inefficient because they represent inferior levels of production than the ones that could be generated given the amount of resources available. On the other hand, points located above the PPF curve are impossible, because they represent bundles of x and y that cannot be manufactured given the initial endowment of resources.

Answer:
The correct answer to the question: What type of sampling is used? In regards to a research study in which American Airlines wishes to know the opinion of its customers related to their two new services, would be: cluster sampling.
Explanation:
In research there are many options to choose from for a researcher to carry out his study and achieve his goals. Among the options is how he/she will select the sample, meaning the group, or groups, that will be used for the study. This selection, of course, will depend on the type of study, and the purpose that is sought. In this case, we have an airline, American Airlines, who wishes to know how its customers are responding to their two new services. Since they cannot ask every single customer they have, or have had, who has used either, or both, of the services, then what they do is select a sample of 130 flights to choose the customers who will respond to their survey. These customers are a small group that represents the larger population of American Airline flyers, and they are selected from the 130 flights, which ensures that they at least have heard of the new services. This is what is called cluster sampling.
