Recently the General Social Survey asked respondents,

“Compared with 10 years ago, would you say that American children today are (1) much better off, (2) better off, (3) about the same, (4) worse off, or (5) much worse off.” Table 12.33 shows opinion responses for 10 of the subjects on three issues: quality of their education, safety of the neighborhoods they live in, and getting health care when they need it.

(a) For each of the following, indicate whether it is a fixed effect, random effect, or response variable: (i) opinion, (ii) issue, (iii) subject.

(b) Test the hypothesis that the population means are equal. Report the P-value, and interpret.

(c) The first five respondents were female, and the last five were male. Analyze these data using both gender and issue as factors.
