  A problem of a new physical model test given observed experimental data is a
typical one for modern experiments of high energy physics (HEP). A solution of
the problem may be provided with two alternative statistical formalisms, namely
frequentist and Bayesian, which are widely spread in contemporary HEP searches.
A characteristic experimental situation is modeled from general considerations
and both the approaches are utilized in order to test a new model. The results
are juxtaposed, what demonstrates their consistency in this work. An effect of
a systematic uncertainty treatment in the statistical analysis is also
considered.
