Exercise

Interpreting the output from an ANOVA

In the last exercise we produced output from the aov() function. This fit_aov object is available in your console and if you want to inspect it again, you can copy summary(fit_aov) in your console. If you inspect the output carefully, you will see a p value smaller than 0.05 for the genre variable. What does this p value mean in the context of the current data?
