Do those elected to the U.S. House of Representatives really "rep resent" their constituents demographically? This was a question of interest in Chance (Summer 2002). One of several demographics studied was religious affiliation. The accompanying table (saved in the USHOUSE file) gives the proportion of the U.S. population for several religions, as well as the number of the 435 seats in the House of Representatives affiliated with that religion. Give your opinion on whether or not the members of the House of Representatives are statistically representative of the religious affiliation of their constituents in the United States.
