Wages and salaries make up only part of a total compensation. Other parts include paid leave, health insurance, and many others. In 2007, wages and salaries among manufacturers in the United States made up an average of 65.8% of total compensation. To determine if this changed in 2008 a random sample of manufacturing employees was drawn. Can we infer that percentage of total compensation for wages and salaries increased between 2007 and 2008?
Sample data lacking.
