Alice tried to see whether she could use her toggle switch therapy to rehabilitate the zombie code 1318 workers. She took 14 zombies, and 14 humans with facial injuries as controls. Half of each group received her original C-gene therapy, whereas the other half received a toggle switch as well. All participants were asked to study a picture of themselves before their injury/zombification. The outcome was how closely (as a percentage) they resembled the photo. The data are in Table 17.6. Fit a two-way linear model to these data to test the main effects of therapy (C-gene vs. C-gene plus toggle switch), species (human vs. zombie) and their interaction. Is each F-ratio significant?
