The article Statistical Evidence of Discrimination (J. Amer. Stat. Assoc., 1982: 773-783) discusses the court case Swain v. Alabama (1965), in which it was alleged that there was discrimination against blacks in grand jury selection. Census data suggested that 24% of those eligible for grand jury service were black, yet a random sample of 1075 called to appear for possible duty yielded only 181 blacks. Using a significance level of 0.01, does this data argue strongly for a conclusion of possible discrimination?
