A t-test for independent samples computed by a researcher on the data from his experiment about the effect of distraction on memory is reported as  t(30) = 2.0 p < .05 1 tail test. Based on this information, what is the effect size evaluated by r2 in this study? (Note: the numerical answers are rounded to 2 decimal places.) A. r2 = 2/30 = 0.07 B. r2 = 2/32 = 0.06 C. r2 = 4/34 = 0.12 D. r2 = 4/30 = 0.13 E. r2 = 4/28 = 0.14 F. None of the above.
