Another type of confidence interval is called a one-sided confidence interval. A one-sided confidence interval provides either a lower confidence bound or an upper confidence bound for the parameter in question. You are asked to examine one-sided confidence intervals. Presuming that the assumptions for a one-mean z-interval are satisfied, we have the following formulas for (1−α)-level confidence bounds for a population mean μ: Lower confidence bound: x¯zασ/n, Upper confidence bound: x¯+zασ/n. Interpret the preceding formulas for lower and upper confidence bounds in words.
