Let us test simple hypothesis about goodness-of-fit of grouped sample to the
theoretical distribution law F(x). Grouped sample of the size n is given with
the boundary points k k
x < x < < x < x 0 1 −1

intervals, 0
x and k
x are the left and right boundaries of the random variable
domain respectively, and the number of observations i
