Question

From the 2016 General Social Survey, when we cross-classify political ideology (with 1 being most liberal and 7 being most conservative) by political party affili- ation for subjects of ages 18–27, we get:

Report the prediction equation and interpret the direction of the estimated effect.
Construct the 95% Wald confidence interval for the effect of political ideology. Interpret and compare to the profile likelihood interval shown.
Conduct the Wald test for the effect of x. Report the test statistic, P-value, and interpret.
