Yes, it's called washout and it is intended to reduce the chance of
the stall happening at the wing-tip where the moment of force is
higher than at the root. In this way the chance of catastrophic wing-
drop at low speed or in wind shear is much less likely.
By the way, the way a wing (or prop blade) is set is called angle of
incidence. Angle of attack is the angle between a aerofoil's chord
line and the relative air flow; incidence is static, attack dynamic.
