Quizplus · Accepted Answer

The sampling distribution of the mean is used to evaluate the reliability of sample means, allowing researchers to determine whether the sample mean is likely to be a good estimate of the population mean. It is not used to set alpha (α), based on an infinite number of z-scores, or known as the 'normal curve'.
