The General Social Survey (GSS) asked a random sample of adults their opinion about whether astrology is very scientific, sort of scientific, or not at all scientific. Here is a two-way table of counts for people in the sample who had three levels of higher education: \begin{array}{ccc} & \text{Degree held} \ \text{Opinion about astrology} & {\begin{array}{l|c|c|c|c} & \text { Associate's } & \text { Bachelor's } & \text { Master's } & \text { Total } \ \hline \begin{array}{l} \text { Not al all } \ \text { scientific } \end{array} & 169 & 256 & 114 & 539 \ \hline \begin{array}{l} \text { Very or sort } \ \text { of scientific } \end{array} & 65 & 65 & 18 & 148 \ \hline \text { Total } & 234 & 321 & 132 & 687 \end{array}} \ \end{array} State appropriate hypotheses for performing a chi-square test for independence in this setting.
