A total of 1220 adults were asked the following question: €œSome people say that because of past discrimination, African Americans should be given preference in hiring and promotion. Others say that such preference in hiring and promotion of African Americans is wrong because it discriminates against Caucasians. What about your opinion€”are you for or against preferential hiring and promotion of African Americans?€ Table 26 compares the adults€™ responses with their ethnicities.

a. Find the proportion of surveyed Caucasians who favored preference in hiring African Americans.
b. Find the proportion of surveyed African Americans who favored preference in hiring African Americans. Compare your result to the result you found in part (a). Why is this comparison not surprising?
c. A student says that Caucasians in the study are more likely to favor preference than African Americans in the study because more Caucasians (134) favored preference than African Americans (77). What would you tell the student?
d. From inspecting the two-way table, a student concludes that 81.0% of all American adults are against preference in hiring African Americans. What would you tell the student?
