Economists use which of the following to prove their claims?
a) scientific theory

b) scientific notation

c) expanded notation

d) population statistics

The correct answer is D.

Economists prove their claims by testing a set of hypothesis, based on a previous and exhaustive study undertaken on a certain matter, through the collection of empirical data. The initial hypothesis will be tested using such data to reach a conclusion: the hyphotesis are either accepted or rejected.

Apart from population statistics, by using econometric techniques, it is possible to conduct inference on sample data, which yields appropiate statistics to study a whole population.
