In August 2003, 56% of employed adults in the United States reported that basic mathematical skills were very important to their job. The supervisor of the job placement office at a 4-year college thinks this percentage has increased, due to the increase in technology in the workplace. They randomly survey 700 employed adults and find that 417 of them feel that math is very important to their job. Use this survey data to test the supervisor's hypothesis, at the \alpha = 0.05 level of significance.
