In February 2014, the United States added 175,000 jobs to the economy. Given this information, what can we say about the unemployment rate of the country? A. It will increase, since an increase in the number of jobs will always result in an increase in the unemployment rate. B. It will not change, since the number of new jobs in the economy has no impact on the unemployment rate. C. It must decrease, since as more jobs are added to the economy, the country's overall unemployment rate falls. D. It may increase, decrease, or not change depending on how many people started searching for jobs during the month. Suppose that in January there were workers in the labor force, with employed and unemployed, implying a 6.6 percent unemployment rate. A month later, there were workers in the labor force, with employed and unemployed. (Notice the number employed went from to , an increase of 175,000.) The unemployment rate in February is nothing%. (Round your response to two decimal places.)
