Confidence interval estimates of a population parameter ________.

A) provide a range of values within which the true value of the parameter is believed to be
B) specify a value that accurately predicts the population parameter
C) eliminates the effect of sampling error
D) are used solely to estimate the value of population variance

Confidence Interval

A range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter with a certain level of confidence.

Population Parameter

A numerical characteristic or measure that describes an aspect of a population.

Sampling Error

The discrepancy between the statistical characteristics of a sample and those of the population from which the sample was drawn.
