Question 7

A recent article in USA today reported that a job awaits only 1 in 3 (33.3%) 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 students had jobs. At a .05 significance level, can we conclude that a larger proportion of students at your school have jobs?

 

What is the null hypothesis for this hypothesis test?
