I want to know the answer to the following question:
How many Oklahomans speak only English at home, as of 2000?
All the background I'm provided with is that "In 2000, 2,977,187 Oklahomans—92.6% of the resident population five years or older—spoke only English at home, a decrease from 95% in 1990.". Is that enough to answer the question?
