4. Adolescents and Social Stress In a study to compare ethnic differences in adolescents’ social stress, researchers recruited subjects from three middle schools in Houston, Texas.25 The students were asked how their family’s socioeconomic status compared with others

(much worse off, somewhat worse off, about the same, better off, or much better off) with the results that follow:

a. Do these data support the hypothesis that the proportion of adolescent African Americans who state that their status is “about the same” exceeds that for adolescent Hispanic Americans?

b. Find the p-value for the test.

c. If you plan to test using a 5.05, what is your conclusion?
