Wall Street set to open lower after strong jobs data

Wall Street was set to open lower on Friday after a strong jobs report strengthened the case for an interest rate hike in the coming weeks. A report from the U.S. Labor Department showed 178,000 jobs were added in the public and private sectors in November, compared with economists' expectation of 175,000. Strength in the labor market and improving inflation are two factors that influence the Federal Reserve's decision on raising interest rates.
