Tutorial 4 - Lesson 2: Randomization test, What is a p-value?, Calculating the p-values - problem with code exercise about ims-tutorials

[IZE85]

I assume there is an issue with the "visualize()" and the "get_p_value()" functions, as also in "Tutorial 4 - Lesson 3: Errors in hypothesis testing" in the subsection "Example: opportunity cost" we have to use these functions and the console still returns me "argument is of length zero"

This code all works for me.
