Choose the significance level (also known as alpha or a) and other options for the test.

Dialog box items

Label for reference treatment: Enter a name for the reference treatment, for example "Approved Drug".

Label for test treatment: Enter a name for the test treatment, for example "New Drug".

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 of the difference between (or ratio of) the means. 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.
