Statistical Power Calculation

This workflow describes how to calculate the Statistical Power (Type II error) from one sample. This is an adaptation of a method used by the attached web site which shows the calculations as they would look in Excel. The workflow contains a number of Sliders that can input different values accounting for Confidence Interval, Alpha, Sample (number), and the Hypothesis Mean (the predicted mean or another real mean). The website below shows the work done in Excel by the author of the website and I was just transforming his work into Knime. Hopefully, I did him justice.
