  Data produced by laboratory Einstein-Podolsky-Rosen-Bohm (EPRB) experiments
is tested against the hypothesis that the statistics of this data is given by
quantum theory of this thought experiment. Statistical evidence is presented
that the experimental data, while violating Bell inequalities, does not support
this hypothesis. It is shown that an event-based simulation model, providing a
cause-and-effect description of real EPRB experiments at a level of detail
which is not covered by quantum theory, reproduces the results of quantum
theory of this thought experiment, indicating that there is no fundamental
obstacle for a real EPRB experiment to produce data that can be described by
quantum theory.
