Please help! There is something about all three graphs that tells us that there are no "dead" batteries, or batteries that last for very few hours and then quit. What is it?

1. The range of the lowest quartile is very small. There are no extreme outliers in the lowest quartile.
2. The second and third quartiles don't have the same range for any particular brand.
3. The large range in the upper quartile.
4. The median for each brand is over 50 hours.
