Here€™s a scatterplot of the production budgets (in millions of dollars) vs. the running time (in minutes) for a collection of major movies. Dramas are plot-ted in red and all other genres are plotted in blue. A separate least squares regression line has been fitted to each group. For the following questions, just examine the plot:

a) What are the units for the slopes of these lines?
b) In what way are dramas and other movies similar with respect to this relationship?
c) In what way are dramas different from other genres of movies with respect to this relationship?
