Question

The article "Determination of Most Representative
Subdivision" (J. of Energy Engr., 1993: 43-55) gave
data on various characteristics of subdivisions that could
be used in deciding whether to provide electrical power
using overhead lines or underground lines. Here are the
values of the variable x = total length of streets within a
subdivision:
1280 5320 4390 2100 1240 3060 4770
1050 360 3330 3380 340 1000 960
1320
530 3350 540 3870 1250 2400
960 1120 2120
450 2250 2320 2400
3150 5700 5220
500 1850 2460 5850
2700 2730 1670 100 5770 3150 1890
510 240 396 1419 2109
a. Construct a stem-and-leaf display using the thou-
sands digit as the stem and the hundreds digit as the
leaf, and comment on the various features of the
display.
b. Construct a histogram using class boundaries 0, 1000,
2000, 3000, 4000, 5000, and 6000. What proportion
of subdivisions have total length less than 2000?
Between 2000 and 4000? How would you describe
the shape of the histogram?

5. Oxygen demand is a term blologists use to describe the axygen needed by fish and other aquatic organisms for survval. The Environmental Protection Agency conducted a study of a wetland area in Marin County, Californla. In this wetland environment, the mean oxygen demand was u=9.9 mg/L, and a= 1.7 mg/L. (Reference: EPA Report 832-R- 93- 005). Let x be a random varlable that represents oxygen demand in this wetland environment. Assume x has a probability distribution that is approximately normal. a. An oxygen demand below 8 mg/L Indicates that some organisms In the wetland environment may be dying. What is the probability that the oxygen demand will fall below 8 mg/L? b. A high oxygen demand can also indicate trouble. An oxygen demand above 12 mg/L may indicate an overabundance of organisms that endanger some types of plant life. What is the probability that the oxygen demand will exceed 12 mg/L?
