(b)
To explain in what way are dramas and other movies similar with respect to this relationship.
(b)
Explanation of Solution
The scatterplot of the production budget and running time for major release movies is given in the question. In the scatterplot, dramas are plotted in red and all other genres are plotted in black. And a separate least square line for each is fitted in the scatterplot. The dramas and other movies are similar with respect to this relationship as costs for movies increase at the same rate per minute as the dramas.
(c)
To explain in what way are dramas different from other genres of movies with respect to this relationship.

Explanation of Solution
The scatterplot of the production budget and running time for major release movies is given in the question. In the scatterplot, dramas are plotted in red and all other genres are plotted in black. And a separate least square line for each is fitted in the scatterplot. The dramas are different from other genres of movies with respect to this relationship as on average dramas costs is about
