[issue24068] statistics module - incorrect results with boolean input

Mark Dickinson added the comment: I wonder if it would be better to reject Bool data in this context? It's not uncommon (and quite useful) in NumPy world to compute basic statistics on arrays of boolean dtype: the sum of such an array gives a count of the `True`s, and the mean gives the
