A state highway department studied the wear characteristics of five different paints at 8 locations in the state.The standard, currently used paint (paint 1) and four experimental paints (paints 2, 3, 4, 5) were included in the study.  The eight locations were randomly selected, thus reflecting variations in traffic densities throughout the state. At each location, a random ordering of the paints to the chosen road surface was employed. After a suitable period of exposure to weather and traffic, a combined measure of wear considering the durability and visibility was obtained (The higher the score, the better the wearing characteristics). Let be the wearing score for paint at the location. The data are given in the table below.   Mark whether the following statements are true/false for this study.    (1).
