Explanation / Answer

Let us first understand the difference between Descriptive statistics & Inferential statistics.

Descriptive statistics uses the data to provide descriptions of the population, either through numerical calculations or graphs or tables. Inferential statistics makes inferences and predictions about a population based on a sample of data taken from the population in question.

In a given study , 1039 adults who were employed full or part time were asked the following question: “If you won 10 million dollars in the lottery, would you continue to work, or would you stop working?” Sixty-eight percent of the respondents said that they would continue to work.This statement is description of the population of employed persons through numerical calculations. This study does not involve  inferences and predictions about a population based on a sample of data taken from the population.

Hence, given study is descrptive.
