Which of these makes an inference in statistics? Is it (A) computing a statistic from the sample? (B) Generating a random sample from a given population. (C) Applying conclusions drawn from a sample of a whole population. Or (D) working out the percentage of the population that exhibits a certain characteristic.

Statistical inference is the process of using data analysis to deduce properties of a population. This means that we’re looking to make conclusions from a sample that could apply to the whole population. The correct answer is therefore option (C). An inference applies conclusions drawn from a sample of a whole population.
