Wetlands offer a diversity of benefits. They provide a habitat for wildlife, spawning grounds for U. S. commercial fish, and renewable timber resources. In the last 200 years, the United States has lost more than half its wetlands. Environmental Almanac gives the percentage of wetlands lost in each state in the last 200 years. For the 30 of the lower 48 states, the percentage loss of wetlands per state is as follows. How are the percentages distributed? Is the distribution skewed? Are there any gaps?

a. These data are fairly symmetric, perhaps slightly skewed right.
b. There is a gap showing that none of the lower 48 states has lost from 10% to 19% of its wetlands.
c. The percentages are concentrated from 20% to 60%.
