This question relates to a famous court case in the USA where for the first time results of
statistical analysis were presented as evidence of discrimination. In 1972 Mr Partida, a
Mexican-American, was convicted of burglary by a jury in a particular county in Texas.
Mr Partida’s lawyers, appealed the conviction on the grounds that the jury must have
been selected in a discriminatory (and thus non-random fashion) because it had a
disproportionately small number of Mexican-Americans on it. They based their argument
on the following two pieces of information. First, a recent census had shown Mexican-
Americans made up 79.1% of adults in the population in that county and that this fact
was widely accepted. Second, in a sample of court cases in the county involving a total of
870 jury members, only 39% were Mexican-Americans. Assume that we will conclude
that jury selection in the county was discriminatory if there is less than a 1% chance

这个问题涉及一个著名案件中，美国在第一次结果
统计分析提出了作为证据的歧视。帕尔蒂达先生于1972年，一个
墨西哥裔美国人，被定罪为入室盗窃由陪审团在某一县在得克萨斯州。
他帕尔蒂达的律师，呼吁定罪的理由是，必须有陪审团
被选中的歧视（因此非随机的方式） ，因为它有一个
不成比例少数墨西哥裔美国人上。他们根据自己的论点
就以下两条信息。首先，最近的人口普查表明墨西哥
美国人占79.1 ％的成人人口的县，并在这一事实
被广泛接受。第二，在抽样法庭案件审理中，县，共涉及
870陪审团成员中，只有39 ％是墨西哥裔美国人。假设我们将结束
这挑选陪审团在县是歧视如果有不到1 ％的机会
抽样比例的39 ％ （或更少）而产生的随机选择的
人口的比例为79.1 ％ 。如果你是法官的美国联邦最高法院
法院，那么您的发现是什么？你会发现，有可能是
歧视在挑选陪审团的县？
