Use to calculate one of the following parameters for a 1-sample equivalence test:

·    Sample size

·    Difference

·    Power

When you enter values for any two of these parameters, Minitab solves for the third. See, Power for equivalence tests for further discussion.

For One-Sample Equivalence Test, you conduct an experiment on a new way to seal potato chip bags. The confidence interval for the difference is not completely within your equivalence interval (-0.42, 0.42), so you cannot conclude that the force that is required to open the new bags is equivalent to the target of 4.2 N (Newtons).

You want to determine whether your sample size of 28 is large enough to provide adequate power for the test. You use Power and Sample Size for 1-Sample Equivalence Test to explore the relationship between sample size, power, and difference for a 1-sample equivalence test.
