The following ANOVA table is from an experiment that had a group receiving a placebo as the no treatment control, a group that received a dose of experimental compound A, another group receiving compound B while a final group received both drugs in combination. Each of the groups contained 10 subjects. The following information has been calculated but important pieces are missing.
| Source of Variation | Sum of Squares | df | Mean squares | F-ratio | P |
| Groups (treatments) | 8.804 | 0.004 | |||
| Error | 10.512 | ||||
| Total | 19.316 |
Given the above table calculate the degrees of freedom (df) column.
We need the df only. please show your work and I will rate your answer for sure. Thank you

A student ran a between-subjects experiment comparing three treatments for depression: cognitive-behavioral therapy (CBT), client-centered therapy (CCT), and a no-treatment condition. Subjects were randomly assigned to the experimental condi- tion. After a sufficient duration on these treatments, the difference in subject’s depression scores pre/post study were measured using a valid depression assessment instrument. The data are summarized in the tables below. Conduct a Oneway ANOVA with α = 0.05 by first completing the values in the lower table, then using...
