16. * Table 13 21 is a SPSS printout based on General Social Survey data combined for the years 1977, 1978, and 1980. The response vanable is an index of attitudes toward pre- marital. extramarital, and homosexual sex. Higher scores represent more permissive atti-tudes. The qualitative explanatory variables are race (0) for whites. I for blacks). gender (0 for males, I for females). region (0 for South. I for non-South), and religion (R =1 for liberal Protestant sect, R2 = 1 for conservative Protestant. R3 = 1 for fundamentalist Protestant sect, R4 = 1 for Catholic, Rs = 1 for Jewish; no religious affiliation when R = Rs = 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 foi atheists and communists.

a) State the regression model for this analysis, and give the prediction equation.

b) Based on the regression parameter estimates, give a profile of a person you would ex- pect to be (i) least permissive. (ii) most permissive, with respect to sexual attitudes.
