gedeck/practical-statistics-for-data-scientists ? reverse-engineered prompt

Build me a clean companion repository for a statistics for data science book, with Jupyter notebooks in both Python and R that teach the main ideas through small examples and exercises.

I want it organized so someone can open the notebooks online, or run them locally without too much setup. Include the data files, a simple way to install the needed environment, and a few docs pages that explain how to use the notebooks and where to start. It should feel like a polished learning resource, not just a dump of code.

If it helps, also make it easy to run in Binder and view notebooks in nbviewer, and keep the project friendly for both Python and R users. Look up current docs online if you need to.
