1. The study cited in the earlier questionreported that: "Thirty-two of the 42 IPS participants (76%) gained competitive employment, compared with 12 of the 43 VRP participants (28%) (2=19.84,df=1, p<.001). That is, veterans with PTSD who participated in IPS were 2.7 times more likely to gain competitive employment than those who received VRP."
2. a) Is the rate ofcompetitive employment significantly different between the IPS vs. VRP groups?Type Y for Yes, N for No
3. Justification: testType T for t-test, C for Chi-square test, p-value
4. b) Is 2.7 a relative risk or odds ratio estimate?Type RR for Relative Risk, OR for Odds ratio. Hint: compute both RR and OR to answer this question.
