During a period of 11 years 800800 of the people selected for grand jury duty were​ sampled, and 6262​% of them were immigrants. Use the sample data to construct a​ 99% confidence interval estimate of the proportion of grand jury members who were immigrants. Given that among the people eligible for jury​ duty, 65.965.9​% of them were​ immigrants, does it appear that the jury selection process was somehow biased against​ immigrants?
