Two-way Anova (3)

In the last exercise we produced our first two-way anova output. The output is stored in the object two_way_fit and is available in your console. If you want to inspect it again, you can copy summary(two_way_fit) in your console. If you inspect the output carefully, you will see a p value smaller than 0.05 for the both genre and continent variables. What does the p value mean for the genre variable? What does the p value for the continent variable mean?

Possible Answers
