The Hall voltage is proportional to the product of the magnetic field, the current, and the carrier charge. If the charge carriers are positive instead of negative, the polarity of the Hall voltage will be reversed. This is because the positive charge carriers will deflect in the opposite direction compared to negative charge carriers due to the Lorentz force. Therefore, the Hall voltage will change sign.
