During a period of 11 years,of 600 people that were selected for grand jury duty, 73% of them were immigrants. Construct a 99% confidence interval for the percentage of grand jury members who were immigrants. The 99% confidence interval is from __ to __. (Round to 3 decimal places as needed.)

Could someone work this out for me so I can look what steps it takes to get the answer and how to do it please?

Thank you
