Question

C4. Suppose we used General Social Survey data to examine the relationship between educational attainment (RDEGREE: 0 = less than high school, 1 = high school degree, 2 = some college or more) and the variable HELPPOOR, which measures support of the statement that the government in Washington should do everything possible to improve the standard of living of all poor Americans. The obtained chi-square is 40.43. Based on an alpha of .05, do you reject the null hypothesis? Explain. helppoor SHOULD GOVT IMPROVE STANDARD OF LIVING? * RDegree Recoded Degree Crosstabulation Count RDegree Recoded Degree Total .00 1.00 2.00 1 GOVT ACTION 30 65 32 127 2. 6 32 41 79 helppoor SHOULD GOVT IMPROVE STANDARD OF LIVING? 3 AGREE WITH BOTH 32 153 126 311 4 6 56 58 120 5 PEOPLE HELP SELVES 14 69 35 118 Total 88 375 292 755

Answer 1

As given , the calculated value of chi-square is 40.43

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

the critical value of chi square at 95% with 8 degree of freedom is 15.507

since 40.43 > 15.507 , so we reject Ho.
