Answer:

If the question is what type of sample the researcher used for his study, he used a random sample.

Explanation:

When conducting a study, one of the steps is to choose the sample of the population that will be studied.

In this case, the researcher used a random sample where all the people in the population have the possibility to participate. As described in this study, all the cars that entered the city were part of the random sample since the survey was not discarding any model, nor access time during the time of the study, since it sought to study what was the type of vehicle with higher income.
