Randomized Hypothesis Test (row-level analysis): DimensionMismatch ERROR

@pdeffebach

Thanks for your time and sharing the resource.

I did not want you to debug the code. But
the solutions you presented created NEW
challenges that no longer were of my
construction, but rather yours.

Solution:

  1. Reconstruct the DF from the source so that
    it was not a cross-tab but single-attribute DF.
  2. I used semi-colons in the combination()
    method to concatenate all array elements.
