A survey was conducted of newlyweds in a country who have a spouse of a different race or ethnicity from their own. The survey included random samples of 1000 newlyweds in Ethnicity A and 1000 newlyweds in Ethnicity B. In the survey, 14% of respondents in Ethnicity A and 23% of respondents in Ethnicity B had a spouse of a different race or ethnicity from their own. At a = 0.01, is there evidence to support the claim that the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own is less than the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own? Let p, represent the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own. Let p2 represent the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own. State the null and alternative hypotheses. OB. HO: P1 SP2 O C. Ho: P1 # P2 O A. HO: P1 P2 Ha: P1 = P2 Ha : P1 2 P2 OF. HO: P1 > P2 OD. HO: P1 2 P2 OE. HO: P1 = P2 Ha : P1 # P2 Ha: P1 SP2 Ha: P1
