Question

Quizplus · Accepted Answer

Probabilities are important in both inferential statistics, where they help to determine the likelihood of a hypothesis being true or false, and in predicting future outcomes, where they can inform decisions about risk and uncertainty. Descriptive statistics, which summarize and describe data, may involve probabilities in certain calculations, but they do not rely on probabilities in the same way that inferential statistics and prediction do. Therefore, choice D (A and C) is the correct answer.
