Question

10. 10.9 [SOC Does support for suicide (“death with dignity") vary by social class? Is this relationship different in different nations? Small samples in three nations were asked whether it is ever justified for a person with an incurable disease to take his or her own life. Respondents answered in terms of a 10-point scale, on which 10 was "always justified" (the strongest support for "death with dignity") and 1 was "never justified" (the lowest level of support). Results are reported here. Mexico Upper Class Middle Class Lower Working Class Class 2 4 4 4 2 10.3 S 10 10 5 9. 3 1 8 3. 8

Answer 1

To test the variation classwise the non paramtrpar kruskal Wallis test is used in r . From the results p value is less than the 0.05( level of significance) . therefore we can conclude that support for sucide vary by the social class .
