1. A repeated-measures experiment and an independent-measures experiment both produce t statistics with df = 20. How many individuals participated in each experiment?

n = 21 for independent-measures and n = 21 for repeated measures

n = 21 for independent-measures and n = 11 for repeated measures

n = 22 for independent-measures and n = 21 for repeated measures

n = 22 for independent-measures and n = 11 for repeated measures

A repeated-measures study and a matched-subjects study are both used to compare two treatments. If each study uses a total of 30 participants, then what are the df values for the two studies?

repeated-measures df = 29 and matched-subjects df = 29

repeated-measures df = 29 and matched-subjects df = 14

repeated-measures df = 14 and matched-subjects df = 29

repeated-measures df = 14 and matched-subjects df = 29
