Final answer:
A federal jury is composed of U.S. citizens who meet certain eligibility criteria and are selected from the community. There are two types of federal juries: grand juries for indictments and petit juries for determining verdicts in civil and criminal trials.
Step-by-step explanation:
The composition of a federal jury usually includes a group of U.S. citizens who are randomly selected from a fair cross section of the community in the district where the federal court is located. To be eligible for jury service, individuals must be at least 18 years old, have a sufficient understanding of English, and have no disqualifying mental or physical conditions. Additionally, they must not have any felony convictions, unless their civil rights have been legally restored.
Federal juries are composed of grand juries and petit juries. A grand jury, which usually consists of 16 to 23 members, is responsible for determining whether there is enough evidence to charge someone with a crime. A petit jury, typically made up of 6 to 12 members, is charged with determining guilt or innocence in both civil and criminal trials.
