In the example comparing length of time on probation by risk level, the average length of time on probation was 11.8 months for moderate risk youth and 16.8 months for high risk youth. Recall that we ran a t-test that had a p-value of 0.002. Below are the 95% confidence intervals for the same averages. How do these compare with our t-test results? What reasons could explain the comparison? 95% CI for Moderate Risk (9.9 months to 13.7 months) 95% CI for High Risk (14.3 months to 19.3 months)
