It is fairly easy to create the sign test.

Create a new column that is a conditional formula. Specify the value 1 if the original data is greater than your target, 0 otherwise (note that I am assuming there are no values equal to the target. If that occurs, most texts recommend removing that observation from the data).

This formula column should have a Nominal modeling type. Now make a distribution of that column. From the red popup, choose Test Probabilities. Typically the hypothesized probabilities are 0.5. You will have two different tests. The Likelihood Ratio test will match most of the "by hand" calculations that are mentioned in text books. Typically, both tests will agree on the conclusion.
