Solution

There is no relationship or very weak relationship between the movie earnings and ratings, since the movie with the 6th spot in the rating being the highest grosser, earning more than two times the second movie, hence there is no relationship or very weak relationship between the movie earnings and ratings

Even the movie with the least rating is not the least earner, even the second highest rated movie has just earned 1/30 times the most earned film
