A confidence interval using the known population standard deviation ________.

A) is the same as the point estimate for the population standard deviation
B) has the least sampling error compared to confidence intervals for mean
C) is the simplest type of confidence interval

Confidence Interval

A set of numbers, taken from sample-based statistics, that is probable to contain the estimated value of an unspecified population parameter.

Population Standard Deviation

A measure of the spread or dispersion of a set of data points in a population.

Sampling Error

The discrepancy between a sample statistic and the actual population parameter, which arises purely by chance from random sampling.
