The formula for constructing a confidence interval estimate of the population mean requires a point estimate of the population mean (A), the standard error of the sampling distribution of the sample mean (B), the confidence level (C), and the sample size (E). However, the value of the population mean itself (D) is not included in the formula, as it is unknown and the goal of the interval estimate is to provide a range of plausible values for it.
