C)representative sample
D)bivariate distribution

Quizplus · Accepted Answer

The statement describes the properties of a normal distribution, which is characterized by its mean and standard deviation. Therefore, if we assume a normal distribution, we can use the empirical rule to estimate the percentage of cases within certain intervals of the mean. This rule states that approximately 68% of cases fall within one standard deviation of the mean, about 95% within two standard deviations, and almost all (99.7%) within three standard deviations. Random sample, representative sample, and bivariate distribution are not relevant to the question.
