  We present the final measurements of the left-right cross-section asymmetry
(ALR) for Z boson production by e+e- collisions and Z boson-lepton coupling
asymmetry parameters Ae, Amu, and Atau in leptonic Z decays with the SLD
detector at the SLAC Linear Collider. Using the complete sample of polarized Z
bosons collected at SLD, we get ALR = 0.15056 +- 0.00239, Ae = 0.1544 +-
0.0060, Amu = 0.142 +- 0.015, and Atau = 0.136 +- 0.015. The ALR=Ae and Ae
results are combined and we find Ae = 0.1516 +- 0.0021. Assuming lepton
universality, we obtain a combined effective weak mixing angle of sin 2 theta
eff W = 0.23098 +- 0.00026. Within the context of the SM, our result prefers a
light Higgs mass.
