Summarize the Multi-Factor Model

You have now created a two-factor model of the reading comprehension and speeded addition factors. Is that better than a one-factor model? Use the cfa() and summary() functions on your new two-factor model of the HolzingerSwineford1939 dataset to show the fit indices.
