Question

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%.

Answer 1

The distribution of wetland loss percentages among states is right-skewed, concentrated between 20% to 60%, with a noticeable gap where no states have lost between 10% to 19% of their wetlands.

Step-by-step explanation:

When looking at the percentage loss of wetlands in each state, we aim to analyze the distribution of these percentages. An examination of the given data indicates that the distribution of wetland loss percentages seems to be concentrated from 20% to 60%, suggesting a right-skewed distribution. This means that more states have wetland loss percentages on the lower end of the spectrum, with only a few states having high wetland loss percentages. Also notable is the presence of a gap in the distribution, specifically, no states have a reported loss between 10% to 19%, which is unusual and amplifies the skewness to the right. The states' wetland loss percentages can be summarized as follows: most are between 20% and 60% with a significant gap between 10% and 19%, and the distribution is right-skewed.

Answer 2

The solution can be defined as follows:

Step-by-step explanation:

Wetland Percentage:

`0] 9\\\\1] None\\\\2] 0 4 7\\\\3] 0 3 5 5 5 7 8\\\\4] 2 2 5 5 8\\\\5] 0 0 1 1 5 9 9\\\\6] 0 8\\\\7] 1\\\\8] 7 7 9\\\\9] 0\\`

• These details are very symmetrical, perhaps pretty biased.
• There might be a gap whereby shows that none of the 48 lowest states have lost 10 to 19% of all its wetlands.
• These statistics were distributed between 20% and 60%.
