About Sample Mean

The sample mean (x-bar) is the average of a sample drawn from a population. It is an unbiased estimator of the population mean.

Formula: x-bar = sum of all values / n

Standard Error: SE = s / sqrt(n)

The confidence interval provides a range of values that likely contains the true population mean.
