One of the assessed outcomes in the Oregon Health Insurance experiment was the percentage of individuals who owed medical debt. Recall that there were 6,387 individuals in the treatment group (lottery winners who were given a chance to enroll in Medicaid) and 5,842 individuals in the control group (those who remained uninsured). The observed percentages of individuals with medical debt were 43.5% in the treatment group and 56.8% in the control group. Perform a statistical test to decide whether Medicaid enrollment improved the medical indebtedness of the studied population. Explicitly spell out all steps of your analysis and interpret the findings.
