1.      Fit a logistic regression model using “d3” (1 = happy or very happy, 0 otherwise) as the dependent variable and place of residence (with rural residence as the reference category) as the independent variable, and interpret the residence coefficient in terms of odds ratios.

2.      In model 2, add controls for age, sex, marital status, education, family income, and self-reported health. Construct a 95% confidence interval for the odds ratio comparing urban and rural residents.

3.      In model 3, test the hypothesis that the effect of place of residence varies depending upon education.
