Abstrakt: We show that the operator $ S = {\upsilon ^{ - 1}}M\upsilon $ denotes the HardyLittlewood maximal operator, is of weak type (1,1) with respect to the measure $ \upsilon (x)w(x)dx$ and $ w$ weights. B. Muckenhoupt's weighted norm inequality for the maximal function can then be obtained directly from the P. Jones factorization of $ {A_p}$ weights using interpolation with change of measure.
