A community thought to be plagued by a toxic spill wanted to show that the incidence of breast cancer is higher in their area than in an area matched to them in all other important health relevant characteristics and demographics, but without exposure to this toxin. It was found that in 20 of 200 adult women in this community, breast cancer was present. In the matching community without the toxin 10 of 150 adult women had breast cancer. Can the community with toxin exposure claim at the = 0.05 significance level that cancer is more prevalent in their area?
