4. (55 pts) You will use data from the 2018 General Social Survey (GSS) to assess the association of attitudes toward immigrants with several other factors. Use letin1a as your dependent variable that asks respondents if they think the number of immigrants should be reduced or increased. Your independent variables are: religR, racecen1R, and rincom16. Rincom16 is an interval variable and you need to transform it to an ordinal variable with the following categories: [1 = 0$ - 29,999$], [2 = 30,000$ - 49,999$], [3 = 50,000$ - 74,999$], [4 = 75,000$ - 109,999$], and [5 = 110,000$ and more]. Carefully examine the values of this variable before recoding it, and examine the other independent variables to make sure that they are categorical. Once you examined your independent variables, conduct the appropriate test of association between your categorical dependent and independent variables and answer the following questions: a. State hypotheses about the relationships you expect to find between your dependent variable and each of the independent variables (15 pts). b. Which measure(s) of association would you use for each relationship? Why? (20 pts) c. Write a short summary of your results for each association (i.e., letin1a & religR, letin1a &
