Ecology: Habitat 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 lower 48 states, the percentage loss of wetlands per state is as follows: 46 37 36 42 81 87 52 24 27 38 27 91 46 9 54 28 35 23 90 72 85 49 48 38 60 46 87 89 67 Make a stem-and-leaf display of these data. Be sure to indicate the scale. How are the percentages distributed? Is the distribution skewed? Are there any gaps? 20 56 73 59 39 74 30 33 50 49 52 42 59 50 35 56 50 31 35
