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. 35 33 35 38 27 45 35 30 90 73 50 38 48 68 59 59 50 60 9 50 24 B9 42 83 51 42 45 87 51 20 Make a stem-and-leaf display of these data.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question
Transcribed Image Text: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.
35 33 35 38 27 45
35 30 90 73 50 38
48 68 59 59 50 60
9 50 24 89
51 20
42 83 51 42 45 87
Make a stem-and-leaf display of these data. (Use the tens digit as the stem and the ones digit as the leaf. Enter NONE I
any unused answer blanks.)
Percent of Wetlands Lost
How are the percentages distributed? Is the distribution skewed? Are there any gaps? (Select all that apply.)
O There is a gap showing that none of the lower 48 states has lost from 10% to 199 of its wetlands.
O The percentages are concentrated from 20% to 60%.
O The percentages are concentrated from 60% to 90%.
O There is a gap showing that none of the lower 48 states has lost from 60% to 69%% of its wetlands.
O These data are fairly symmetric, perhaps slightly skewed right.
O These data are strongly skewed left.
O There are no gaps in the data.
