Use the following information to answer the final set of questions:

You did a different sample of students at City College and SF State.

In the random sample of 400 City College students you found that 192 of them had jobs.

Of the 300 students you sampled at State, 108 had jobs.

You want to determine if there is a statistically significant difference in the population proportions of students who work at the two schools.

Use a subscript of c for City College and a subscript of s for State.

Find the null and alternative hypothesis. Include all symbols (there should be 5 total), in both hypotheses.
