Which of these describes an inference in statistics? (A) Computing a statistic from the sample. (B) Working out the percentage of the population that exhibits a certain characteristic. (C) Applying conclusions drawn from the sample of the whole population. Or (D) generating a random sample from a given population.

Statistical inference is the process of using data analysis to deduce properties of a population. This process is trying to deduce properties that can apply to the whole population. Option (C) relates this: applying conclusions drawn from a sample of a whole population. A statistical inference applies conclusions drawn from a sample of a whole population.
