Table 13.21 shows output for GSS data with y =

index of attitudes toward premarital, extramarital, and homosexual sex, for which higher scores represent more permissive attitudes. The categorical explanatory variables are race (0 for whites, 1 for blacks), gender (0 for males, 1 for females), region (0 for South, 1 for non-

South), and religion (r1 = 1 for liberal Protestant sect, r2 = 1 for conservative Protestant, r3 = 1 for fundamentalist Protestant sect, r4 = 1 for Catholic, r5 = 1 for Jewish;

no religious affiliation when r1 = · · · = r5 = 0).

The quantitative explanatory variables are age, education

(number of years), attendance at church (higher values represent more frequent attendance), and a variable for which higher values represent greater intolerance of freedom of speech for atheists and communists.

(a) Based on the parameter estimates, give a profile of a person you would expect to be (i) least permissive,

(ii) most permissive, with respect to sexual attitudes.

(b) Summarize your main conclusions from studying the output.
