4. Consider the following data set on the top 20 small cruise ships in the world as of 2012. The 4 primary variables are ratings (scores) from passenger surveys. A score of 100 is a perfect score. The ships were rated on the quality of their on-ship activities (Itineraries), off-ship activities (Excursions), and food. They were also given an overall rating.
