Two television stations have made efforts using profiles to promote the adoption of “forgotten” children – orphans who have physical or mental handicaps. Oklahoma City’s station KOCO helped to place 92 out of 119 children it profiled in comparison with NYC’s WCBS, which placed 21 out of 35 (Time, May 2, 1983). Because the techniques employed in presenting the profiles likely differ for the two television stations, we might wish to compare their rates of success in placing the children for adoption. Do the data provide sufficient evidence to indicate a difference in placement success rates between stations KOCO and WCBS? Test using =0.05.
