95%CI= 95% Confidence Interval of the difference. Bold indicates p<0.05. Table reports the predicted outcome in the control and intervention groups at the mean of the controls; the third column in each set reports the coefficient on winning the lottery with 95% confidence intervals. Models were estimated using mixed-effects multi-level regression models controlling for the following covariates: number of schools to which students applied, gender, race/ethnicity (Latino vs. not), native language, being born in the United States, grade point average in 8th grade, parental education, parental birthplace, parental employment, family structure, parenting style, and interview month.
