CU Educational Attainment Differences in First & Second Gen Hispanics & Asians Discussion
In this chapter, we examined the difference in educational attainment between first- and second-generation Hispanic Americans and Asian Americans based on the proportion of each group with a bachelor’s degree. We present additional data from the Pew Research Center’s 2013 report, measuring the percentage of each group that owns a home (Frankfort-Nachmias, & Leon-Guerrero, 2018, p. 231).First-Generation Hispanic Americans (N = 899), 43% own a homeSecond-Generation Hispanic Americans (N = 351), 50% own a homeFirst-Generation Asian Americans (N = 2,684), 58% own a homeSecond-Generation Asian Americans (N = 566), 51% own a homeSource: Pew Research Center, Second-Generation Americans: A Portrait of the Adult Children of Immigrants.

Is there a significant difference between first-and second-generation Hispanic American populations?
Yes
No
Question 2 3 Points What is the difference? -2.33 2.33 0.0198 0.07 Question 3 2 Points Is there a significant difference between first-and second-generation Asian populations?

No
Question 4 2 Points What is the difference? 3.50 -3.50 0.0004 0.07
In 2016, the Pew Research Center surveyed 1,799 white and 1,001 black Americans about their views on race and inequality. Pew researchers found “profound differences between black and white adults in their views on racial discrimination, barriers to black progress and the prospects for change.” White and black respondents also disagreed about the best methods to achieve racial equality. For example, 34% of whites and 41% of blacks said that “bringing people of different racial backgrounds together to talk about race” would be a very effective tactic for groups striving to help blacks achieve equality.Test whether the proportion of white respondents who support this tactic is significantly less than the proportion of black respondents.

π₁ ≠ π₂
π₁ = π₂
μ1 = μ2
μ1 ≠ μ2
Question 7 2 Points Calculate the Z statistic and test the hypothesis at the 0.05 level. What is the Z Statistic?
3.50
-3.50

Question 8 2 Points What is your decision (step 5 in hypothesis testing)? Do you accept or reject the null hypothesis? Accept Reject
We compare the proportion who indicated that it was “very important” to be born in this country to be American for two GSS 2014 groups: respondents (1) born in the United States (native born) and (2) not born in the United States (foreign born). Test the research hypothesis that a higher proportion of native-born respondents than foreign-born respondents indicated being born in the United States was “very important” to be American. Set alpha at 0.05.
