You are interested in learning whether the habitat of urban wildlife affects nutritional preferences. To study this, you measure the amount of pizza consumed by rats living in the subway and those living in the sewers. You find that 3 subway rats consume 1, 1, and 4 slices of pizza/week each; meanwhile, 3 sewer rats consume 3, 4,and 5 slices of pizza/week each. What is the SSE (sum of squared errors) for within-group pizza consumption? Round your answer to the nearest 0.1
