A teacher claims that only 35% of the students at
USC work while attending school. The dean thinks
that the teacher has underestimated the number of
students with part-time jobs. A random sample of 81
students shows that 39 have jobs. Do the data
indicate that more than 35% of the students have
jobs? Use a 5% level of significance.
