# Question: One Sided One Mean t Intervals Presuming that the assumptions for a one mean

One-Sided One-Mean t-Intervals. Presuming that the assumptions for a one-mean t-interval are satisfied, we have the following formulas for (1 − α)-level confidence bounds for a population mean μ:

Lower confidence bound: x-bar tα · s/√n.

Upper confidence bound: . x + tα · s/√n.

Interpret the preceding formulas for lower and upper confidence bounds in words.

Lower confidence bound: x-bar tα · s/√n.

Upper confidence bound: . x + tα · s/√n.
