Below is an ANOVA summary table for a 3x5 ANOVA reflecting the data of 12 subjects. Some of the df are incorrect, and/or it may be missing degrees of freedom. Use the blank space below to fix the incorrect and/or provide the missing degrees of freedom (do not do more than this). What type of ANOVA design does this table represent?
