A reseаrcher is interested in evаluаting the effectiveness оf a new treatment fоr PTSD. On a standardized measure оf PTSD, the mean score among untreated individuals diagnosed with this disorder is μ = 25 and the standard deviation is σ = 12. The researcher draws a random sample of size n = 49 from a large group of individuals who have recently received the new treatment technique. In this sample, the group mean on the standardized PTSD measure is M = 20. Does the new treatment significantly reduce the level of depression from that expected among untreated individuals diagnosed with depression? Conduct a two-tailed Z-test with alpha set at .05 to test the hypothesis that the treatment is effective. Use the following information that the M = 20, where μ = 25, σ = 12, and n = 49. What is the standard error of the mean?
