Statistics

It was found that during a period of 11 years in Hidalgo County, Texas, 870 people were selected for grand jury duty and 39% of them were Americans of Mexican ancestry. Among the people eligible for grand jury duty, 79.1% were Americans of Mexican ancestry. Use a .01 significance level to test the claim that the selection process is biased against Americans of Mexican ancestry. Does the jury selection appear to be fair?

Identify the null hypothesis, alternative hypothesis, test statistic, P-value or critical value(s), conclusion about null hypothesis, and final conclusion that addresses the original claim?
