Choose the significance level (also known as alpha or a) and other options for the test.
Risk level of claiming equivalence when it is not true (alpha): Specify the significance level for the test. 0.05 is the most common choice.
Use (1 - 2 alpha) x 100% confidence interval: Check to use an alternative method to calculate the confidence interval for the difference between the mean and the target. The alternative method may give you the same upper confidence limit and lower confidence limit as the default method. The confidence level for the alternative method is always smaller than that of the default method. For example, if a is 0.05, then the confidence level for the alternative method is 90%, rather than 95% for the default method.
