A job awaits only one in three new college graduates

[xdongx1]

A recent article reported that a job awaits only one in three new college graduates. The major reasons given were an overabundance of college graduates and a weak economy. A survey of 200 recent graduates from your school revealed that 80 of them had jobs. At the 0.03 significance level, can we conclude the larger proportion of recent graduates of your school who have jobs is greater than on in three?

One fact that is required is the total number of recent graduates from the school. For example if it is 200, then exactly 40% have jobs!
