Friday’s job numbers is the last monthly employment report before the U.S. Federal Reserve meets on Sept. 16-17, when an announcement on interest rates is widely expected.

Wall Street closed sharply lower on Tuesday, with renewed concerns about China’s economy pushing major indexes down almost 3 percent and intensifying fears of a long-term selloff.
