Question

2. Income inequality in the United States is a complex matter, and people have diverse and con- flicting ideas on how to best address it. For this exercise, we present GSS 2014 SPSS analysis of political party identification and the variable HELPPOOR, which measures support of the statement whether the government in Washington should do everything possible to improve the standard of living of all poor Americans. HELPPOOR is measured on a scale legovernment action to 5 = each person should take care of binsel . A score of 3 indicates agreement to both strateg es a. What percentage of Democrats indicate that government action is necessary to help poor Americans? What percentage of Republicans indicated the same? b. The chi-square obtained is 119.53. Based on an alpha of.01, what can you conclude about the relationship between political party identification and HELPPOOR? Government Action 69 Agree to Both 142 People Help 4 Themselves Total 33 324 163 Democrat Independent40 1877 15 13 Republicar Total 50 15 84 303 10 70 124 78 115 112

Explanation / Answer

a) % of democrats indicate that government action is necessary =69/324=0.2130 ~21.30%

% of republicans indicate that government action is necessary =15/245 =0.0612~ 6.12%

b)

for degree of freedom =(rows-1)*(column-1) =(3-1)*(5-1) =8

for 8 degree of freedom and 0.01 level; crtiical value =20.09

as test statisitc is higher then critical value ; we reject null hypothesis ;we have sufficient evidence to conclude that political party identiifcation and HELPPOOR are dependent(related)
