Anne Colton has a renovation business which uses painters to do custom paint jobs for house exteriors. She is trying to get a better idea of her cost structure to be able to bid on contracts as there has been new competition entering her neighbourhood from the downtown area. She has traditionally used the square footage of the houses she's worked on; but noticed that the amount of time taken also differed on the last 2 projects which had a lot of windows and doors, which requires a lot more preparation work. Information for her last 12 jobs are as follows.
