The correct statement that was established by the Northwest Ordinance is:
Only territories with a population of at least 60,000 could apply for statehood.
The Northwest Ordinance of 1787 set forth a plan for the admission of new states from the Northwest Territory and outlined certain fundamental rights, including the requirement for a minimum population for statehood. It also addressed the importance of education but did not establish that the educational system would be funded by the central government. Regarding slavery, it stated that slavery was prohibited in the Northwest Territory, but it did not guarantee freedom for all escapees.
