The General Social Survey conducted a poll of 668 adults in which the subjects were asked whether they agree that the government should prohibit smoking in public places. In addition, each was asked how many people lived in his or her household. The results are summarized in the following contingency table.

Test the hypothesis of independence. Use the α = 0.01 level of significance.

I don't know what I did wrong, am I perhaps using the wrong type of test?
