Schier. American Politics Quarterly. Vol. 21, 1993, p. 1251. The pre- diction equation was =.350 + 0111D+.094REL+.005NW +.0051NC +063GEN -.167PAR where REI. = religion = 1 for non-Catholics. GEN = gender = 1 for women, PAR = party = for Democrats, ID = ideology is the member's ADA score (ranging from 0 at most conservative to 100 at most liberal), NW = nonwhite is the percentage nonwhite of the member's district, and INC = income is the median family income of the member's dis- inct

a) Interpret the effect of percentage nonwhite.

b) Interpret the effect of gender

c) Interpret the coefficient for party. Does this imply that. ignoring the controls, Democrats are less likely than Republicans to take a pro-choice position?
