2. When convicts are released from prison, they have no money, and there is a high rate of recidivism (the released prisoners return to crime and are arrested again.) Would providing income support to ex-convicts during the first months after their release from prison reduce recidivism? The Department of Labor ran a randomized controlled experiment to find out. The experiment was done on a select group of convicts being released from certain prisons in Texas and Georgia. Income support was provided, like unemployment insurance. There was a control group which received no payment, and a treatment group that received payments. 592 prisoners were assigned to the treatment group and of them 286 were rearrested within a year of release. 154 were assigned to the control group, and of them 76 were rearrested within a year of release. Did income support reduce recidivism? a. Test at the a = 0.05 level of significance. Use the p-value approach. State each step clearly.
b. Construct a 95% confidence interval between the survival rates for the two groups. Interpret the answer OX 1-«= oc a/2= 26/27 = A 95% confidence interval for p1 – P2 is: ((P1-P2) Z«/21 P1(1-21) P2(1-P2) + n1 n2 Interpret the interval:
