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.

83 59 35 30 33 45
45 50 59 87 35 50
37 20 68 48 71 51
51 60 38 87 38 9  
42 90 42 50 27 27  

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 in any unused answer blanks.)

How are the percentages distributed? Is the distribution skewed? Are there any gaps? (Select all that apply.)

a)The percentages are concentrated from 20% to 60%.
b)These data are strongly skewed left.
c)There are no gaps in the data.
d)These data are fairly symmetric, perhaps slightly skewed right.
e)There is a gap showing that none of the lower 48 states has lost from 10% to 19% of its wetlands.
f)There is a gap showing that none of the lower 48 states has lost from 60% to 69% of its wetlands.
g)The percentages are concentrated from 60% to 90%.
