A study was made of movies in 2005. For each movie, the following were recorded: its budget (the amount it cost to make, in millions of dollars), its running time (from start to finish, in minutes), and the genre (drama, comedy, action, etc.). The scatterplot below shows the budget vs. running length for all movies. Two regression lines are shown on the scatterplot, for predicting budget from running length. The lower line is for movies of the "drama" genre, while the upper line is for movies of all other genres. Which of the statements below do you most strongly agree with? (a) The difference in budget between dramas and other movies of the same length remains constant as the movies get longer. (b) Dramas cost less to make than other movies of the same length, and that difference increases as the movies get longer. (c) Dramas cost more to make than other movies of the same length, and that difference increases as the movies get longer. (d) Dramas cost more to make than other movies of the same length, and that difference decreases as the movies get longer. (e) Dramas cost less to make than other movies of the same length, and that difference decreases as the movies get longer.
