In Zn-doped single-crystal YBa{sub 2}Cu{sub 3{minus}{ital x}}Zn{sub {ital x}}O{sub 7{minus}{delta}} we show that the normal-state Hall angle varies as cot{theta}{sub {ital H}}={alpha}{ital T}{sup 2}+{beta}{ital x}, as predicted by Anderson ({ital T} is temperature). The existence of two distinct relaxation time scales ({tau}{sub {ital H}}{similar to}1/{ital T}{sup 2} and {tau}{sub tr}{similar to}1/{ital T}), required by experiment, precludes all multi-band Drude-type models. A number of puzzling features of the Hall effect in the cuprates are resolved with the new analysis. We also report an improved measurement of the scattering cross section of Zn in the CuO{sub 2} planes.
