Are college students more likely than high school students to have a part-time job? A recent study found that 21 out of a random sample of 51 college students had part-time jobs and that 12 out of a random sample of 40 high school students had part-time jobs. At the 5% level of significance, do these samples provide evidence that college students are more likely than high school students to have a part-time job? Be sure to clearly state the null and alternative hypothesis, calculate the test statistic and p-value, state the conclusion of the test, and interpret the result in context.
