Question

1. Wetlands offer a diversity of benefits. They provide 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 20 73 59 35 50 87 52
24 27 38 56 39 74 56 31 27 91 46 9
54 52 30 33 28 35 35 23 90 72 85 42
59 50 49 48 38 60 46 87 50 89 49 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?

Answer 1

The question is asking to calculate the percentage that the data is distributed and base on my further research and further investigation on the table, the possible answer would be 9%.  I hope you are satisfied with my answer and feel free to ask for more if you have questions 

Answer 2

Explanation:

Percentage of wetlands lost in each state is shown in stem and leaf plot as 0-10, 10-20 etc.

We have gaps for stem 1.

Stem and leaf plot would be as follows:

Stem Leaf

0 9

1

2 0 3 4 7 7 8

3 0 1 3 5 5 5 6 7 8 8 9

4 2 2 6 6 6 8 9 9

5 0 0 0 2 2 4 6 6 9 9

6 0 7

7 2 3 4

8 1 5 7 7 9

9 0 1

Let us calculate the summary for the data as

Minimum: 9

Maximum: 91

Count: 48

Sum: 2407

Mean: 50.15

Median: 48.5

Mode: 46, 35, 50

Standard Deviation: 20.72

Variance: 429.1

Skewness = 0.466538

Yes this is skewed.
