A major automotive paint manufacturer has a "panel farm" on the coast of Florida. The purpose of this "farm" is to expose paints to different environ mental conditions (sun, rain, salt, and sand) to test durability. A set of panels from three test formulations was sent to the farm and left out in the elements for 6 months. After that time they were rated on their appearance using a scale of 1-10 ( 1 being good).
The data is in exposure .txt.
(a) Calculate summary statistics for each formulation.
(b) Graph the data.
(c) Summarize your findings.
