Oil prices fell on Friday, settling at their lowest since January after data showed the U.S. economy added fewer jobs than expected last month, and weak Chinese economic data added more pressure. Brent crude futures settled down $2.71, or 3.41 percent, to $76.81 a barrel. U.S. West Texas Intermediate crude futures settled down $2.79, or 3.66 percent, at $73.52.
