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 in Exercises One-Sided One-Mean t-Intervals. Presuming that the assumptions for a one-mean t-interval are satised, we have the following formulas for (1-a)-level confidence bounds for a population mean µ: • Lower confidence bound: x-ta s/ √n• Upper confidence bound: x + ta s/ √n Interpret the preceding formulas for lower and upper confidence bounds in words.
