A researcher conducts an independent-measures, two-factor study using a separate sample of n= 15 participants in each treatment condition. The results are evaluated using an ANOVA and the researcher reports an F-ratio with df = 1, 84 for factor A and an F-ratio with df = 2, 84 forfactor B. a) How many levels of factor A were used in the study? b) How many levels of factor B were used in the study? c) What are the df values for the F-ratio evaluating the interaction?
