A community action group has heard complaints that African American and Hispanic students are more likely to be suspended (either in-school or out-of-school) than other students. The superintendent of schools offers to review the files of students in grades 9-12. The school system has 39,000 students in grades 9-12: 58 percent African American, 12 percent Hispanic, and 25 percent White.

2. State the alternative hypothesis and the null hypothesis the superintendent should test.
