Research is being conducted to determine if a large supermarket is discriminating against African Americans. For the supermarket, thirty percent of the employees that are eligible for a merit raise are African American. Since the implement of this new merit raise program 17 out of 60 employees that received the merit raise are African American. Is there evidence to support a claim of discrimination based on race (the proportion of African Americans who receive the merit raise is less that it should be)?

How should we write the alternative hypothesis?
