We examine the relationship between educational attainment and agreement to the statement, "Immigrants take jobs away from people who were born in America" as measured in the GSS 2010. Responses to IMMJOBS are measured according to the same five-point scale (as FINDEPND in Question 4).
a. Set alpha at .05 and test the null hypothesis of equal means.
b. If alpha were set at .01, would your decision remain the same?
