prop.pass = proportion of students who passed the exam num = number of students who sat the exam urban = if school is in urban area (1 = urban, 0 = rural) %dis = % pupils at school defined as "disadvantaged" (by parental income). Students either are or aren't disadvantaged.

Is the following regression suitable to determine if there is a difference in the rural and urban exam pass rate, controlling for %dis?

glm(prop.pass ~ urban + %dis, weights = num, family = quasibinomial, 
    data = exam_df)

Secondly, I get the output:

Coefficients:
  (Intercept)         urban          %dis  
       3.5123        -0.1244        -0.8605

Degrees of Freedom: 3156 Total (i.e. Null); 3154 Residual (73 observations deleted due to missingness) Null Deviance: 55930 Residual Deviance: 27650 AIC: NA

Do I interpret this as being from an urban rather than rural area is associated with an decrease in the log odds of passing the exam of 0.1244?
