Question:

Gross We have data in HollywoodMovies2011 on the world gross (total worldwide box office income) for all 2011 Hollywood movies, although for this problem we€™ve removed movies classified as €˜€˜Adventure€ or €˜€˜Fantasy€ because there were only one and two movies, respectively, in each category. The relevant summary statistics and visualization are shown. If we consider this year as a sample of all movies, do we have evidence that the mean world gross differs by movie genre?
