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.

A random sample of 1200 U.S. college students was asked, "What is your perception of your own body? Do you feel that you are overweight, underweight, or about right?" The two-way table summarizes the data on perceived body image by gender. \(\begin{array}{ccc} & \text{Gender} \\ \text{Body image} & {\begin{array}{l|c|c|r} & \text { Female } & \text { Male } & \text { Total } \\ \hline \text { About right } & 560 & 295 & 855 \\ \hline \text { Overwerght } & 163 & 72 & 235 \\ \hline \text { Underweight } & 37 & 73 & 110 \\ \hline \text { Total } & 760 & 440 & 1200 \end{array}} \\ \end{array}\)

What percent of respondents feel that their body weight is about right?

A random sample of U.S. adults was recently asked, "Would you support or oppose major new spending by the federal government that would help undergraduates pay tuition at public colleges without needing loans?" The two-way table shows the responses, grouped by age.

\(\begin{array}{ccc} & Age \ Response & {\begin{array}{l|r|r|r|r|r} & 18-34 & 35-49 & 50-64 & 65+ & Total \\ \hline Support & 91 & 161 & 272 & 332 & 856 \\ \hline Oppose & 25 & 74 & 211 & 255 & 565 \\ \hline Don't know & 4 & 13 & 20 & 51 & 88 \\ \hline Total & 120 & 248 & 503 & 638 & 1509 \end{array}} \ \end{array}\)

Do these data provide convincing evidence of an association between age and opinion about loan-free tuition in the population of U.S. adults?
