B) nonparametric statistics
C) the central limit theorem
D) robustness

Quizplus · Accepted Answer

The central limit theorem states that when sample sizes are at least 30, the distribution of the sample means will be approximately normally distributed, regardless of the underlying population distribution. This means that parametric statistics can be used to make inferences about the population parameters, as long as the sample size is large enough. Nonparametric statistics and robustness refer to different concepts and are not relevant to this question.
