A crew of meteorologists measured the amount of snowfall in 7 different parts of a mountain town. They each recorded the amount
of snow in inches and arranged their data from least to greatest. The number of inches that fell were 2, 2, 3, 4, 5, 6, and 6. The mean amount of snowfall was 4 inches. What is the MAD (mean absolute deviation) rounded to the nearest tenth?
