Which of the following is not a part of the formula for constructing a confidence interval estimate of the population mean?

A) A point estimate of the population mean.
B) The standard error of the sampling distribution of the sample mean.
C) The confidence level.
D) The value of the population mean.

Confidence Interval

A gamut of values generated from sample statistics, which is likely to envelop the value of an unseen population parameter.

Standard Error

A metric that quantifies the spread of sample averages around the mean of the entire population.

Confidence Level

A measure expressed as a percentage that indicates the probability that a confidence interval contains the true parameter value.
