F. A researcher suggests that gun ownership and ideology may
shape evaluations of the Republican Party. The dependent variable
is a feeling thermometer scale of the Republican Party, with
responses ranging from 0(cold/negative) to 100 (warm/positive).
This researcher defines a dummy variable, “conservative,” which is
coded 1 for self-described conservatives and 0 for nonconservatives
and another dummy variable, “owner,” coded 1 for respondents who
own a gun and 0 for respondents who do not. The regression to be
estimated is y=a+b1(owner)+b2(conservative). Here are the results
(the standard errors for the regression coefficients are in
parentheses): y = 30.0 + 7.2(owner) + 24.8(conservative) (0.70)
(0.67) R2=0.23
What is the effect of gun ownership on ratings of Republicans,
controlling for conservatism?
Is it reasonable to infer that, in the population, gun owners
give Republicans higher ratings than do nonowners? Defend your
reasoning.
