For each of the following studies: (a) identify the sample size(s), (b) state if we have a significant difference based on the calculated t-value given at alpha = .05 and alpha = .01. In the two-sample case, assume equal sample sizes, and (c) calculate r2 if significant. One-sample t test: t(30) = 2.050 Two sample independent measures t-test: t(18) = 1.50 One-sample t-test: t(35) = 1.75
