Compute the true stress and the logarithmic strain using the data given below and plot the results on log-log paper. then, find the plastic strength coefficient σ0 and the strain-strengthening exponent m. the yield strength and the ultimate strength after the specimen has had 20 percent cold work. the original diameter of the test specimen is 0.5 in. and the original length, lo = 2.000 in. the following data was obtained for the

Two researchers are attempting to create a new psychotherapy protocol that more reduces panic attacks. they believe that they have succeeded and are now in the clinical trial period of their protocol's development. they are working with several cohort groups, some of which have been through the new protocol, while others have done the standard protocol currently recommended. if these researchers are interested in evaluating the difference in the percentage of test subjects who successfully decreased their panic attacks in 2 months on the new protocol versus the percentage of test subjects who successfully decreased their panic attacks in 2 months with the traditional protocol, which of the following statistical tests would be most appropriate? a. analysis of variance (anova) b. correlation c. chi-square test d. paired t-test e. independent t-test
