The Census Bureau proposed to use statistical sampling to supplement the door to door count for the 2000 Census. The Supreme Court ruled that
(a) sampling would reduce bias, so it can be used in the Census
(b) sampling is against the law, so it cannot be used at all in the Census
(c) sampling is not an accepted scientific method, so it cannot be used at all in the Census
(d) sampling cannot be used to say how many seats in Congress each state has, but can be used for all other Census purposes
